- The portuguese version of the self-regulation scale: psychometrics, measurement invariance, and associations with antisocial variables among youthPublication . Pechorro, Pedro; Salguero, Timothy B.; Nunes, Cristina; DeLisi, Matt; Cyders, Melissa A.Self-regulation is the basic capacity to regulate one’s thoughts, emotions, and behaviors. The aim of the present study is to examine the psychometric properties of the Self-Regulation Scale (SRS) among male and female Portuguese youth participants (N = 559 youth, M = 16.51 years, SD = 1.07, range = 14–20 years). The three-factor model composed of the Emotional, Cognitive, and Behavioral regulation subscales obtained adequate fit, although the fit of the second-order model was also acceptable. Internal consistency as measured by the alpha and omega reliability estimators was good. Significant associations were found with psychometric measures of relevant constructs (e.g., self-control, psychopathic traits, criminogenic cognitions), and external criterion-related variables (e.g., engaging in activities against the law, alcohol and drug abuse). Cross-gender measurement invariance was supported, with females scoring significantly higher on the Cognitive regulation subscale, and males scoring significantly higher on the Emotional regulation subscale. The findings support the use of the SRS to validly and reliably measure self-regulation in Portuguese youth.
- The Dickman impulsivity inventory: Validation and measurement invariance among Portuguese young adultsPublication . Pechorro, Pedro; Revilla, Rebecca; Resende, Miguel; Abrunhosa Gonçalves, Rui; Nunes, Cristina; Cyders, Melissa A.The Dickman Impulsivity Inventory (DII) measures impulsive personality related to both negative and positive behaviors and characteristics. The main aim of the present study was to examine the psychometric properties of the DII among a Southern-European sample of Portuguese young adults. Our convenience sample (N = 429, M = 22.11 years, SD = 3.35, range = 18–42), composed of women (n = 237, M = 22.08 years, SD = 3.35, age range = 18–42) and men (n = 192, M = 22.14 years, SD = 3.34, range = 18–35), was collected from a university context. The two-factor latent structure of the DII composed of functional and dysfunctional impulsivity was supported, although three items had to be removed due to low standardized loadings, and strong cross-gender measurement invariance was established. Our analyses of the DII also provided evidence of criterion-related validity, known-groups validity, and internal consistency/reliability. Our findings support the use of the DII among Portuguese young adults.
- Weinberger adjustment inventory Portuguese version: a study of cross-cultural adaptation and measurement invariancePublication . Pechorro, Pedro; Shircliff, Katie; DeLisi, Matt; Simões, Mário R.; Cyders, Melissa A.We examine the psychometric properties of the Weinberger Adjustment Inventory (WAI) from a modern psychometric perspective, including second-order models, better estimation of reliability, and measurement invariance, among a sample of young adults (N = 610, M = 21.33 years, SD = 3.09 years) from Portugal. Results indicated that only the four-factor intercorrelated confirmatory models of the WAI Distress and Restraint scales, and the two-factor intercorrelated confirmatory models of the WAI Defensiveness scales showed adequate fits. The WAI showed good reliability and distinctive correlates with other psychometric measures and criterion variables. Cross-gender measurement invariance was established. Our findings support the WAI as a valid and reliable measure.
