The general purpose of the current study was to analyze and replicate the DAPP-BQ and DAPP-SF psychometric properties in a large Spanish sample using a calibration and validation sample.
The DAPP-BQ is derived from the factorization of 100 personality pathology descriptors, and has 18 traits: Submissiveness (SUB), Affective Instability (AIN; called Affective Lability in previous studies), Anxiousness (ANX), Insecure Attachment (IAT), Cognitive Distortion (COG), Identity Problems (IPR), Low Affiliation (LAF; called Social Avoidance in previous studies), Oppositionality (OPP), Narcissism (NAR), Stimulus Seeking (STS), Callousness (CAL), Rejection (REJ), Conduct Problems (COP), Restricted Expression (REX), Intimacy Problems (INP), Compulsivity (COM), Suspiciousness (SUS), and Self-Harm (SHA).
The short form of DAPP-BQ (Dutch language version), called DAPP-SF, was derived by van Kampen et al.
Structural Equation Modeling (SEM) has been used to assess each DAPP-BQ scale.
05) for each DAPP-BQ scale in both separate groups (calibration and validation), and simultaneously for the whole sample.
The means, standard deviations, kurtosis, skewness and alphas for the 18 DAPP-BQ (3) scales including the 290, 136 and 90-items forms are shown in Table 1.
DAPP-BQ and DAPP-SF mean differences between studies
Maximum likelihood confirmatory factor analyses were conducted over the variance-covariance matrices of each DAPP-BQ single scales in the three versions of the test for both random groups (1 and 2).
In this study we tested that the DAPP-BQ dimensions were higher in patients with psychosis than in siblings of this type of patients, as we expected.
SSLS, however, had a more adaptive personality, reflected by their low scores on DAPP-BQ.
In this study we found that a DAPP-BQ pathological personality profile characterized by high scores on the dimensions of affective lability, anxiousness, submissiveness, social avoidance, identity problems, oppositionality, narcissism, and restricted expression, can distinguish between siblings who had more schizotypal features and those who had less.
