SCID-II, temperament scales of the TCI |
%WL |
PD at T0 (20.4%): paranoid (2%), schizoid (2%), narcissistic (4.1%), histrionic (2%), borderline (8.2%), obsessive-compulsive (2%), avoidant (4.1%), dependent (4.1%). Presence of PD was not associated with %WL at T1. On temperament scales, ↑HA and P were associated with greater %WL at T1. In the predictive model, ↑P predisposed to greater %WL. When classified into normative groups by P (low vs. medium/high scores), the group with low scores achieved lower %WL than the medium/high scoring group. |

|
SCID-II |
Reduction in BMI, %WL, and %EWL |
28.5% exhibited at least one PD at T0. PD at T0 was not related to change in weight at T1. |

|
SCID-II |
Weight loss, compliance with diet, rules, and exercises, percentage attendance at consultations |
PD at T0 (11.7%): narcissistic (6.9%), histrionic (1.7%), antisocial (1.2%), passive-aggressive (1.2%), dependent (0.6%). Narcissistic PD had a negative association with weight loss at T1, T2, and T3 and with compliance with diet and exercises, overall compliance, and attendance at consultations. In a predictive model, narcissistic PD was associated with weight loss at T1. |

|
MMPI-2-RF |
%WL, %EWL, non-adherence (failure to attend consultation) |
↑BXD, RC9, aggression and aggression-revised (T0) were associated with lower %WL. ↑BXD, RC4, JBP and Disc-R, substance abuse, and aggression (T0) were associated with non-adherence. In predictive models, lower %WL was associated with ↑BXD, RC9, and aggression and nonadherence with ↑BXD, RC4, JBP, and Disc-R. |

|
MMPI-2-RF |
SC, PSD, and MAEB |
Somatic concerns scales and EID (T0) were correlated with SC at T1 and T2. EID measures were associated with SC at T2 and with PSD at T1 and T2. EID and BXD scales were associated with MAEB at T3. Measures in the domain thought dysfunction and some measures of somatization were associated with MAEB at T3. |

MMPI-2 MCM-III |
BMI |
MMPI-2: ↑K was predictive of less BMI reduction at all assessment times. MCM-II: in a 1-factor predictive model, ↓C was predictive of greater BMI reduction (T1). In a 2-factor model, ↓C and ↑schizotypal were predictors of BMI reduction at T2 and T4 and ↓C and ↑schizoid were predictors of BMI reduction at T3. |

MMPI-2 |
Challenging-to-manage patients
|
Challenging-to-manage patients had ↑VRIN, F, Fb, and Fp and ↓K and S (validity scales) and ↑depression and paranoia (clinical scales). |

|
TCI-R |
WL (50% or greater of EW) and metabolic results |
↑C was associated with losing more than 50% of EW and with %EWL (predictive model), but was not predictive of comorbidities during the postoperative period. |

|
TCI |
%EWL (weight at T0 – postoperative weight) x100/ EW T0 |
↓P associated with less WL at T3 and posterior consultation. P and NS were positively and ST was negatively correlated with WL at T2 and T3. In CO beyond 24 months, P remained predictive of greater %EWL. |

TCI |
BMI, vomiting, and bulimic behavior |
Greater WL was associated with ↑SD. Patients with ↑ST had a stronger tendency towards less vomiting (≤ 1 per week). |
