Adaptation of Collins ’ Revised Adult Attachment Dimensional Scale to the Chilean Context Adaptação da Escala Dimensional Revisada de Apego Adulto de Collins para o Contexto Chileno

The Adult Attachment Revised Scale is a measure of relationship attachment that contains three dimensions: closeness, dependence and anxiety. In Study 1, the scale was translated and applied to a sample of 420 university students in order to assess reliability. In addition, the scale criterion validity was estimated through measures of self-perception and affectivity. The results of Study 1 supported the internal consistency of two dimensions of attachment, but dependence was lower than expected (α = .62). A confi rmatory factor analysis was conducted and failed to reach a convergent fi t, thus demonstrating that two of the items in dependence were considered problematic. In Study 2, diffi cult items in Study 1 were reworded and the new version of the scale was applied to 81 participants. The results of two subsequent CFAs showed adequate fi t of the scale and increased internal consistency with this new wording (α > .73), which replaced the expression “depend on others” by “getting help from others”, which is a better construct representation of the meaning of dependence in the context of attachment closeness. Therefore, not only did we adapt the three dimensions of the attachment scale, but also provided evidence of its validity related to locally adapted instruments.

Ever since Bowlby´s pioneering research (1979/1989) the study and assessment of attachment has been essential to understand the innate development of human close emotional bonds, from infancy and throughout adult development, and old age (Collins & Feeney, 2013).At present, the theory and description of childhood patterns of anxiety (and recovery) after separation from the primary caretaker (Ainsworth, 1979;Verissimo et al., 2011), has been extended to the comprehension of adult affective bonding, the study of romantic attachment styles, and models of the self and others in the context of close relationships, among others (Collins & Feeney, 2004;Ford & Collins, 2010;Mikulincer & Shaver, 2007;Mota & Matos, 2009).Collins (1996) developed a scale assessing continuous attachment dimensions in adulthood, going beyond earlier trends deriving discrete categories equivalent to specifi c attachment styles (Bartholomew & Horowitz, 1991;Hazan & Shaver, 1987) which although different from one another are potentially related (Collins, 1996).Similarly, the Experiences in Close Relationships (ECR; Brennan & Shaver, 1998;Fraley, Waller, & Brennan, 2000) is a newer instrument than Collins´s scale, based on empirical analysis of previously existing questionnaires which generated two distinct and also continuous attachment dimensions: anxiety and avoidance.But, although the ECR is widely used in relationships research, and is adapted to some South American countries such as Chile and Brazil (Guzmán & Contreras, 2012;Paiva & Figueiredo, 2010), it is a measure that does not allow targeting more specifi c aspects of security, like an individual´s comfort with closeness or dependence in a continuous manner; since it only represents the unsecure realms of attachment.Therefore, to date, the Adult Attachment Scale (AAS, Collins & Read, 1990) and its revised version (AASR, Collins, 1996) is a useful measure to incorporate in our local context when the aim of research is to assess adult attachment, particularly in the continuous dimensions of closeness, and comfort with depending on others, as well as anxiety in close relationships.
Similarly, research addressing romantic attachment usually incorporates other affective and cognitive measures that are related to the nature of close relationships in order to inquire the associations of adult attachment with related constructs such as self-esteem, relationship quality, cognitive beliefs about the partner, and the like (see for example Collins, Ford, Guichard, & Allard, 2006;Feeney & Collins, 2001).Nevertheless, we also included other variables that have been extensively studied in the social and mating literature, and that are potentially related to the dimensions of attachment in the context of adult close relationships.Mate value, reactivity to jealousy, and aggression, which are seldom assessed in association to attachment (but see Cooper, Shaver, & Collins, 1998;Fletcher, Simpson, Thomas, & Giles, 1999) were integrated in the investigation and adaptation of the AASR in Chile.
According to Collins and Read (1990), the attachment system is a cognitive representation of how individuals relate to others throughout their lifetime, as well as how others have responded to social interaction and close relationships with the individual (working models of the self and others).Childhood styles are similar to adult attachment: secure individuals feel loved and valued, they are comfortable with intimate relationships and can depend on others; avoidant persons are well-off free from emotional dependence on others, and do not care about whether they are accepted by others or not; preoccupied individuals want to form signifi cant relationships with others but are worried about being rejected and unloved (Collins & Feeney, 2010).The dimensions of attach-ment proposed by Collins and Read (1990) decompose the classical secure-unsecure categories of attachment mentioned above, according to theoretical and empirical predictions, arriving to three continuous scales.A person´s comfort with close and intimate relationships (close); the individual´s feeling that they can count on others, and that others would be around when in need of them (depend); the person´s level of fear that others would leave or reject them (anxiety; Collins, 1996).
In the fi rst study we review the relationships among attachment dimensions proposed by Collins and Read (1990) and other affective and relational variables (Collins, 1996;Collins, Ford, Guichard, & Feeney, 2006;Cooper et al., 1998), replicating and adding to the hypothetical predictions about the construct validity of the AASR.We used for this purpose particular attachment related instruments and other mating variables that have already been adapted to the Chilean context.We also performed a confi rmatory factor analysis (CFA) on the structure of the scale, which led us to conduct an additional confi rmatory investigation with a completely new sample in Study 2.

Study 1
Adult attachment can be conceptualized as internal working models regulated by social input (Collins & Read, 1990;Hazan & Shaver, 1994;Shaver, Collins, & Clark, 1996) or how individuals have come to view themselves as worthy of love and affection throughout development (model of the self), as well as how comfortable the person feels establishing close and intimate relationships (model of others).Accordingly, the interpersonal experiences that an individual has faced in other aspects of relationships serve to sustain his or her actual mental models of attachment as an adult (Hazan & Shaver, 1994).
There are many predictions that can be drawn about the dimensions of attachment, and the way other psychological constructs would be represented in individuals holding distinct attachment patterns."Adults enter relationships with a history of interpersonal experiences and a unique set of memories, beliefs, and expectations that shape how they think and feel about their relationships and how they behave in those relationships" (Collins, Ford, Guichard, & Allard, 2006, p. 201).
The continuous dimensions of attachment were initially drawn-out from the classical types, and it was predicted that secure attachment would involve high scores on the close and depend dimensions, and low scores on anxiety.The anxious type was expected to be characterized by low scores on close and depend subscales, and high anxiety scores.While the avoidant type, was expected to attain low scores on all the attachment dimensions: close, depend and anxiety (Collins & Read, 1990).
In addition to the above predictions, it was hypothesized that the components of the model of the self, portrayed in the close and depend scales, would be positively correlated with variables that indicate an affi rmative selfperception, such as self-esteem, mate value components, positive affect and perceived relationship quality.The close and depend dimensions, on the other hand, would be expected to be inversely associated to variables indicative of negative views of the self, such as aggression, jealousy, and negative affect.And fi nally, the model of others portrayed in the anxiety scale, was expected to correlate in a positive way with aggression, jealousy, and negative affect (see Collins, Ford, Guichard, & Allard, 2006;Collins & Read, 1990;Cooper et al., 1998).

Sample
A total of 452 participants completed the attachment scale, but we eliminated the responses of 28 participants that did not answer all the items in the scale: one participant that did not report demographic data, and three participants under the age of 18. Therefore our sample size for Study 1 was N = 420 (27.1% men), with an average age of 28.3 years (SD = 10.59), and ranging from 18 to 65 years of age.In order to test the predictions between AASR subscales and the above mentioned affective variables, different subsamples completed some of the construct validity measures, which are detailed in the next subsection (see additional correlated measures on Table 1).
For the analysis of the discrete attachment categories, 34 cases were eliminated which overlapped by their score on more than one attachment style (see Collins & Read, 1990).

Instruments
Adult Attachment Scale Revised (AASR).The AASR (Collins, 1996) was back-translated into Spanish following the criteria suggested by Triandis and Berry (1980).A bilingual collaborator with a background in Educational Sciences, translated the scale into Spanish, and then a bilingual Psychologist translated the scale back into English.A graduate student and the fi rst author revised both versions of the scale, trying to maintain the conceptual meaning of each item and its underlying construct, and setup the Chilean version of the instrument.The dimensions of attachment were maintained in their three original scales: Close, evaluating comfort with closeness and intimacy (items 1, 6, 8, 12, 13, 17); depend, measuring reciprocal availability of others when needed (2,5,7,14,16,18); and anxiety, evaluating the amount of worry about being left alone and unloved (3,4,9,10,11,15).There are a total of 18 items, six on each dimension and they are scored on a scale from 1 to 5 (1-not at all characteristic of me, 5-very characteristic of me).Items 2, 7, 8, 12, 13, 16, 17 and 18 are reversed scored.
Rosenberg's Self-Esteem Scale (RSE).The Chilean adapted version of Rosenberg´s (1965) 10 item questionnaire was used, which includes 10 statements (scored on a scale from 1-strongly disagree to 4-strongly agree) tapping into a global concept of self-esteem (Rojas- Barahona, Zegers, & Förster, 2009).It´s internal consistency for the current sample was adequate (see Table 1).
Positive Affect and Negative Affect Schedules (PA-NAS).Is a measure of 20 affective adjectives developed by Watson, Clark and Tellegen (1988), and adapted locally by Dufey and Fernández (2012).The adjectives are scored on a scale ranging from 1 -very little or nothing at all, to 5 -extremely, 10 of them portray positive affect (PA) and 10 of them negative affect (NA).As it can be observed on Table 1, both scales reached optimal reliability levels.
Mate Value Components.The Chilean adaptation (Fernández, Muñoz-Reyes, Dufey, Buccioni, & Cid, in press) of the Mate Value Components (MVC; Fisher, Cox, Bennett, & Gavric, 2008) is composed of 22 statements about different realms of mating success, sociality, resources, and parenting.Answers are given using a 7-point scale (1 = strongly disagree to 7 = strongly agree).For the current application the internal consistencies can be observed on Table 1.
Jealousy Reactions.The inventory created by Dijkstra, Barelds, and Groothof (2010) of jealousy evoking partner behaviors was used to assess a global score of reactivity to jealousy evoking situations.The local adapted version of the questionnaire was used (Fernández, Pavez, & Dufey, in press).This instrument contains 42 questions asking participants "how jealous would you feel if…" the partner engages in various real-live and Web-based interactions with third persons of the opposite sex.The responses are assessed on a fi ve-point scale ranging from 1 = not jealous to 5 = very jealous (see Table 1 for the internal consistency of the current study).
Perceived Relationship Quality Components (PRQC).An abbreviated version of the PRQC (Fletcher, Simpson, & Thomas, 2000) was used in the study which was adapted to Chile by Schmitt et al. (2004).It is composed of six face valid questions about satisfaction, commitment, intimacy, trust, passion, and love.The answers are given on a scale ranging from 1 (nothing at all) to 7 (completely).It´s internal consistency for the current sample was adequate (see Table 1).
Buss and Perry Aggression Questionnaire (BPAQ).Is a measure of aggression widely used internationally (Buss & Perry, 1992) tapping into four dimensions: (a) physical aggression, (b) verbal aggression, (c) anger, and (d) hostility.It includes 29 items that are scored on a Likert type scale (1-extremely uncharacteristic of me, 5-extremely characteristic of me).It was adapted locally by Figueroa Rey, Ramírez Troncoso, and Santis Doyhamboure (2005).For the current study, verbal aggression is not included in the analysis since it reached unacceptable low levels of internal consistency (Cronbach´s alfa < .5;see Table 1).response items are expected to have (due to an ordinal measurement level), all analysis were run with Robust Maximun-Likelyhood methods for parameters estimation (Byrne, 2006).Multivariate LM Test analysis were simultaneously performed with CFA, in order to obtain modifi cation indices that could orient which parameters could be freely estimated in subsequent specifi cations of the model, in case of a model misfi t.Consequently, we considered S-B χ 2 for non-normal distributed samples (Satorra & Bentler, 1988), and CFI (Bentler, 1990; > .94),RMSEA (Hu & Bentler, 1999; < .7),and the 90% C. I. robust statistics to decide model fi t.

Reliability
As shown in Table 2, Cronbach's alpha showed satisfactory internal consistencies for the anxiety subscale, followed by close and depend subscales.Additionally, a test-retest analysis was performed with a subsample of participants that completed the scale 60 days after the initial application (n = 30, women = 73.3%),indicating signifi cant and high levels of temporal stability for all subscales (see Collins & Read, 1990 for comparable indices).

Procedure
All methods and procedures of this study were approved by the Ethical Committee of the fi rst author´s institution.Participation was achieved in two manners: (a) completing paper and pencil questionnaires containing an informed consent, demographic questions and all the measures; (b) through an online platform, that begun with downloading of the informed consent, completing a demographic questionnaire, followed by the attachment scale and other measures of individual differences.Participation was absolutely voluntary and without compensation.

Data Analysis
We used SPSS 20.0 to analyze the data on Study 1. Descriptive statistics on demographic and all the individual measures were estimated in frequencies and percentages for categorical data, and mean and standard deviations for the continuous measures.For the construct validity, and test-retest stability analyses, we estimated one-tailed Pearson correlation coeffi cients among the dimensions of the scale and the other variables.Internal consistency was estimated using Cronbach´s alpha.For the CFA we used EQS 6.2.Because of non-normal distribution that likert-
Similarly, as Table 3 shows, the categorical types of attachment originally derived from cluster analysis by Collins and Read (1990), showed the predicted empirical configuration of the dimensions of attachment that underlie the AASR.Secure attachment was indicative of significantly high levels of the close and depend dimensions, and signifi cantly low levels of anxiety, in comparison to the highest levels of anxiety attained in the anxious type.Anxious attachment differed signifi cantly from the secure type, by its low scores on the depend dimension.And fi nally, the avoidant type showed the lowest intensities on all the dimensions of attachment.Correlations among Attachment Dimensions and other Affective Variables.As the close and depend dimensions of attachment imply more self-worth, security and comfort in social situations, as well as a positive view of others and the world, we expected positive associations among close and depend subscales and: self-esteem, mate value, positive affect, and the perceived quality of relationships, whereas negative associations were predicted between those subscales and: aggression, jealousy reactivity, and negative affect.On the other hand, since the anxiety dimension is as associated with a tendency to worry of being rejected or abandoned in relationships, we hypothesized positive correlations for this subscale and jealousy reactivity, negative affect, and the affective and cognitive aspects of aggression.Finally, negative relationships between anxiety and self-esteem, positive affect, mate value, and quality of relationships were predicted.The results confi rmed most of the hypothesized associations, showing positive and signifi cant correlations among close as well as depend dimensions and: self-esteem, mate value, and quality of relationships; whereas these attachment dimensions correlated inversely with hostility.Depend was negatively associated to physical aggression, and the anxiety dimension was positively related to jealousy reactivity, anger and hostility; and it showed negative correlations with self-esteem and mate value (see Table 1).

Factor Analysis
In order to test the theoretical structure of the AASR, a CFA was performed specifying a three factor model.Since a convergent solution was not obtained, we run again the analysis dropping items 2 and 5 of the dependence subscale (which were problematic on the fi rst analysis).This decision was made after considering both statistical and substantive criteria: (a) the relative low alpha value of the dependence subscale; (b) the alpha value of the total subscale was improved if those items were deleted; and (c) both items contained a direct translation of "dependence" which may had led to construct imprecision.Therefore an evaluation of language adequacy of the translated items suggested that the meaning of "dependence" may have a bad connotation in the local context.The result of the second CFA showed an improved but still not a good fi t of the model (S-B χ 2 =292.75;df = 101; p < .001;relative χ 2 = 2.89; values below 5 are acceptable, see Schumacker & Lomax, 2004); TLI = .89;CFI = .91;RMSEA = .067;90% I.C. = .058-.076 (see Table 4 for factor loadings).

Discussion Study 1
The AASR reached satisfactory reliability indexes, as seen in both internal consistency and test-retest analysis.Nevertheless, the test-retest sample size was much reduced in comparison to the total sample, so this is a limitation to the estimation of the temporal stability of the attachment scale.Similarly, the depend subscale had acceptable but lower alpha values, suggesting taking with caution this result in further analysis.
Regarding validity of the AASR, we fi rst looked at the interrelations among its subscales, fi nding a positive association among the close and depend dimensions, and a negative correlation between both of them and anxiety.Secondly, the continuous subscales showed the expected confi guration into the attachment types: the secure type classifi ed individuals with high levels of close and depend, but low levels on the anxiety dimension; the anxious type reached high levels of anxiety and close, but low levels of depend; and the avoidant type characterized individuals with low levels on all the dimensions of attachment.These fi ndings reinforce the close associations that exist among the AASR dimensions, although there are discrete differences between them, as it is consistent with previous research (Collins & Read, 1990).
Additionally, we sought to test several hypotheses regarding construct validity of the AASR, fi nding that both depend as well as the close subscales were positively associated with self-esteem, mate value and quality of relationships, and negatively correlated with hostility.This convergence is not surprising as both subscales of the AASR are correlated, implying that as people tend to feel more self-worth, secure and comfortable in social situations, and have a positive view of others and the world, they also perceive themselves as more effi cient and are more self-acceptant in their relationships, having a greater subjective estimation of their individual possibility to mate, as well as better quality of romantic relationships (Collins, Ford, Guichard, & Allard, 2006).Additionally, the closer and more dependent a person is, the less he/she is prone to hostility or the tendency to have negative appraisals about others and situations, which is characteristic of the accompanying lower levels of physical aggression for the depend dimension (Collins, Ford, Guichard, & Feeney, 2006).
The anxiety dimension was positively associated with jealousy reactivity, anger and hostility, and correlated negatively with self-esteem and mate value.This means that people that are more worried of being rejected or abandoned in relationships, are also more jealous in romantic relationships (interpreting more behaviors from their partner as potentially mistrustful), and they experience increased levels of the affective and cognitive dimensions of aggression.On the other hand, they also feel a smaller amount of self-worth, are less secure and comfortable in social situations, and have a poorer self-estimation of their individual value as partners.
However, one limitation to the evidence of validity provided by the previous analysis is the varying subsample sizes that completed the comparison instruments, going from almost half the complete sample for jealousy, affectivity and mate value, to less than a quarter of the sample answering to the self-esteem and aggression scales.
Regarding factor analysis, we failed to fi nd a model adjustment of the AASR through a CFA even after dropping problematic items of the depend subscale (items 2 and 5), a possibility that was suggested by the low internal consistency values on the subscale.In order to keep the original conformation of the AASR, we therefore sought to revise and modify language adequacy of those problematic items, and we tested the theoretical structure of the scale in a new sample on Study 2.

Study 2
Due to reliability problems of the depend subscale which could partially explain the bad adjustment of the AASR in the CFA we run in Study 1, we generated a new version of the instrument with a modifi ed translation of the word "dependence" on items 2 and 5.In this version of the scale, we realized that the word dependence in the Chilean context has a strong negative meaning, referring to a lack of autonomy and self-suffi ciency.Consequently, the correct conjugation of the Spanish adjective "apoyarme" (getting support) was used in items 2 and 5, to refer to dependence.
Thus, in this second study we expected to improve the construct validity of the scale modifying the language of two of the items of the depend dimension, and we expected to arrive to an acceptable fi t of the Chilean version of Collins' AASR (1996).

Sample
The sample of Study 2 was conformed of 89 participants (24.7% men), with a mean age of 29.4 years (SD = 8.78, range = 18 -55), 8 subjects which had missing data were dropped off the analysis.

Instruments
We applied general demographic questions and the modifi ed version of the AASR.

Procedure
We used an online platform following the same procedures of Study 1.

Reliability
Cronbach's alpha for each subscale was .73(Closeness), .80(Depend), and .87(Anxiety), indicating an improvement in the internal consistencies for all subscales and particularly for the depend dimension, which was the more problematic result as seen in Study 1.

Factorial Validity
The fi rst CFA we ran did not show a better model adjustment than the one observed in Study 1 (S-B χ 2 = 200.125;df = 132; p < .001;relative χ 2 = 1.51;TLI = .86;CFI = .88;RMSEA = .079;90% I.C. = .056-.100), so we looked at modifi cation indices that could explain this poor result.We identifi ed a problematic correlation between measurement error terms of items 15 and 10, and 15 and 5 (when a zero correlation between error terms is expected), as well as a cross-loading of item 5 in factor 1 (when it was expected to only have a factor loading in factor 2), which could be accounting for the lack of CFA adequacy, but made theoretical sense if one considers the overall meaning of these items (Byrne, 2006).The adjustment indicator values of the second CFA improved to a marginally signifi cant good fi t of the model (S-B χ 2 =170.618;df = 130; p < .01;relative χ 2 = 1.31; variance adjusted χ 2 = 39.88,df = 30, p = .10;TLI = .91;CFI = .93;RMSEA = .062;90% I.C. = .032-.085), which we estimated as an acceptable adequacy of the scale in the local context (see Table 4 for factor loadings).

Discussion Study 2
The aim of Study 2 was to test the theoretical structure of the AASR, after modifying the translation of items 2 and 5, which showed to be problematic after considering both statistical (relatively low alpha values) as well as substantive (language adequacy) criteria.The fi rst CFA showed a model misfi t, and when looking at modifi cation indices that could improve model adequacy in a new CFA, we found a correlation between error terms of items 15 ("I want to get close to people, but I worry about being hurt") and 10 ("When I show my feelings for others, I'm afraid they will not feel the same about me"), as well as item 15 and 5 ("I am comfortable depending on others").This implies some degree of content overlapping of those items, a fi nding that should be considered in further studies aimed to assess model adequacy of the AASR through CFA, in a similar context.We also found a crossloading of item 5 on factor 1, which belongs to the close subscale (when it only should load on factor 2 corresponding to the depend subscale).Since internal consistency of the depend subscale improved after revising item translation in Study 2, we can consider the possibility that, in the present context, the meaning of this item is not exclusively under the construct that underlies the depend subscale, but it still implies some degree of closeness.
Summing up, the results of Study 2 suggest that the Chilean version of the AASR is consistent with the threedimensional theoretical model that is intended to assess, provided that some overlapping between items 15 and 10, and 15 and 5 is evidenced; as well as a cross-loading of item 5 on the close dimension, in addition to its original load on depend.
However, the reduced sample size of Study 2 in comparison to Study 1, for conducting a confi rmatory factor analysis constitutes a limitation of this investigation that should be kept in mind when using the attachment scale in the local context.

General Discussion
In the present study we sought to adapt and provide evidence of construct validity of the AASR in the Chilean context.The results of the fi rst study yield appropriate psychometric properties of the attachment dimensions in their internal consistency, temporal stability, and interrelations, although two items on the depend scale were a little problematic.Similarly, the attachment types resulted in the theoretically expected confi gurations, as well as the projected associations with convergent and divergent validity measures.
The results of two CFAs in Study 1, derived in a slight change in the wording of items 2 and 5 of the depend dimension, which were tested on a new sample in Study 2. This analysis initially yielded an unfi t of the model until two correlated errors (which was probably due to similar meaning), as well as an item accounted for by two factors, were both included in the model.
The construct validity of the Chilean adaptation of the AASR showed the predicted convergent relationships of the model of the self (depend as well as close) with self-esteem, mate value and quality of relationships.In the case of self-esteem, it was crucial to replicate the positive association of this construct with close and depend, since RSE is a face valid measure of a positive self-concept (Collins & Read, 1990).Similarly, the associations of self-esteem with close a bit higher in magnitude than self-esteem and depend, shows and appropriate differentiation of these two sub-dimensions of attachment; while the inverse relationship of RSE and anxiety with a similar moderate magnitude, suggests that the fear of being rejected or unloved was related to having a negative self-concept, confi rming the strength of the AARS to tap into the model of the self and others.Mate value and perceived relationship quality, which are specifi c measures of success in attracting the opposite sex and having social skills, as well as experiencing positive romantic relationships, respectively, they all did show a positive association with close and depend and no correlation to anxiety.This suggests that in the area of mating, the model of the self is related to the perceived competence of the individual in romantic relationships, while the fear of rejection -prototypical of the model of others-is not important for this fi gure of self-effi ciency in the mating realm (Collins & Read, 1990, and see Collins, Ford, Guichard, & Allard, 2006).An additional piece of construct validity on the model of the self was the lack of association of the dimensions of the AASR with the affect scales, indicative of a differentiation of the cognitive representations of the self and others which would be separated of the general affective approach to the world of the individual.
Additional convergent evidence of the pertinence of the AASR to the local context comes from the confi rmation of positive associations of the model of others portrayed in the anxiety dimension, with jealousy, and different aspects of aggression; while the close and depend dimensions correlated inversely with these aspects of the self.Collins, Ford, Guichard, and Allard (2006) predicted elsewhere that adults with a negative model of others (high in anxiety, i.e. preoccupied) would experience intense levels of jealousy and confl ict in relationships, which may be attributable to their lack of confi dence in the love and intimacy of others.Indeed, in our results, jealousy reactivity (a continuous measure of how varying degrees of suspicion of a partner´s interaction with the opposite sex may evoke jealousy) only correlates with the dimension of anxiety, and it is not associated with close and depend, which may be indicative of the lack of confi dence in social acceptance and proximity of others to the self.On a similar way, the dimensions of aggression, which are highly related to a negative model of others, were associated in a positive direction with the dimension of anxiety, confi rming the proposition that attachment patterns are schemas of how one "experiences, expresses and copes with distressing emotions" (Cooper et al., 1998(Cooper et al., , p. 1380)).Indeed, it is precisely in terms of affective expressions of aggression where the negative model of others more strongly differentiates itself from the model of the self, with anger directly correlating with the dimension of anxiety.Nevertheless, in the cognitive basis of the attachment system, anxiety (or the negative view of others) was positively correlated with hostility, which is a persuasive cognitive scheme to perceive the world in a negative way, and others as having negative intentions towards the self.Divergently, the cognitive perception of others as hostile and having a negative attitude to the individual, showed a moderate and inverse association with the concept of the self, confi rming the predicted confi guration of aggression with respect to the attachment dimensions that constitute the AASR.
Across the two studies we found limitations related to the need of more optimal sampling that must be considered for future research: (a) we had a very reduced size of the test-retest subsample, and some of the criterion validity samples; (b) the sample size of the second study constitutes a limitation to large sample theory behind Structural Equation Modeling, and more specifi cally CFA (Byrne, 2006); (c) the gender distribution of our samples was highly biased towards women, with only close to 30% of men responding to the AASR in both studies.Thus, we cannot be certain that in a more gender equitable sample the results of the scale may remain similar to what we found.
In conclusion, we estimate that the Chilean version of the AASR has acceptable psychometric properties, allowing its use in the local context.This study also adds up evidence of construct validity to preexisting studies on the area.Nevertheless, we encourage further research aiming at replicate our fi ndings, which may include larger and more gender equitable sample sizes (particularly for CFA); and other cognitive and affective constructs potentially related to attachment working models.
