The Bergen-Yale Sexual Addiction Scale (BYSAS): Longitudinal Measurement Invariance Across a Two-Year Interval.
The Bergen-Yale Sexual Addiction Scale (BYSAS; [1]) is arguably the most popular questionnaire at present for assessing sex addiction. Employing Confirmatory Factor Analysis (CFA) and treating item scores as ordered categorical, we applied Weighted Least Square Mean and Variance Adjusted Chi-Square (WLSMV) extraction to investigate the longitudinal measurement and structural invariance of ratings on the BYSAS among 276 adults (mean = 31.86 years; SD = 9.94 years; 71% male) over a two-year period, with ratings at three yearly intervals. Overall, there was support for configural invariance, full loading, full threshold, the full unique factor invariance; and all structural (latent variances and covariances) components. Additionally, there was no difference in latent mean scores across the three-time points. The psychometric and practical implications of the findings are discussed.
期刊介绍：
Psychiatric Quarterly publishes original research, theoretical papers, and review articles on the assessment, treatment, and rehabilitation of persons with psychiatric disabilities, with emphasis on care provided in public, community, and private institutional settings such as hospitals, schools, and correctional facilities. Qualitative and quantitative studies concerning the social, clinical, administrative, legal, political, and ethical aspects of mental health care fall within the scope of the journal. Content areas include, but are not limited to, evidence-based practice in prevention, diagnosis, and management of psychiatric disorders; interface of psychiatry with primary and specialty medicine; disparities of access and outcomes in health care service delivery; and socio-cultural and cross-cultural aspects of mental health and wellness, including mental health literacy. 5 Year Impact Factor: 1.023 (2007)
