The current study examined whether the Avoidance and Fusion Questionnaire for Youth (AFQ-Y; L. A. Greco, W. Lambert, & R. A. Baer, 2008), a self-report measure of psychological inflexibility for children and adolescents, might be useful for measuring psychological inflexibility for adults. The psychometric properties of the AFQ-Y were examined…

The Reflective Functioning Scale (RFS) was developed to assess individual differences in the ability to mentalize attachment relationships. The RFS assesses mentalization from transcripts of the Adult Attachment Interview (AAI). A global score is given by trained coders on an 11-point scale ranging from antireflective to exceptionally reflective.…

Deficits in gratification delay are associated with a broad range of public health problems, such as obesity, risky sexual behavior, and substance abuse. However, 6 decades of research on the construct has progressed less quickly than might be hoped, largely because of measurement issues. Although past research has implicated 5 domains of delay…

Of the several measures of optimism presently available in the literature, the Life Orientation Test (LOT; Scheier & Carver, 1985) has been the most widely used in empirical research. This article explores, confirms, and cross-validates the factor structure of the Chinese version of the LOT with ordinal data by using robust weighted least…

There has been an exponential increase of interest in the dark side of human nature during the last decade. To better understand this dark side, the authors developed and validated a concise, 12-item measure of the Dark Triad: narcissism, psychopathy, Machiavellianism. In 4 studies involving 1,085 participants, they examined its structural…

Thin-ideal (or media) internalization is an important eating disorder risk factor that has become a central target of many prevention programs. However, evidence for its valid assessment in young, mixed-gender, adolescent samples is limited, and the current study is the first to explore the psychometric properties of the 30-item Sociocultural…

The Center for Epidemiologic Studies Depression Scale (CES-D) is one of the most widely used measures of depressive symptoms in research today. The original psychometric work in support of the CES-D (Radloff, 1977) described a 4-factor model underlying the 20 items on the scale. Despite a long history of evidence supporting this structure,…

Five studies document the validity of a new 8-item scale designed to measure "positivity," defined as the tendency to view life and experiences with a positive outlook. In the first study (N = 372), the psychometric properties of Positivity Scale (P Scale) were examined in accordance with classical test theory using a large number of…

The construct of emotion dysregulation increasingly has been used to explain diverse psychopathologies across the lifespan. The Difficulties in Emotion Regulation Scale (DERS; K. L. Gratz & L. Roemer, 2004) represents the most comprehensive measure of the construct to date and exhibits good reliability and validity in adults; however, the…

The underlying structure of the Postconcussion Syndrome Questionnaire (PCS) was evaluated in a large sample of 1,116 medical and psychiatric patients. Balancing internal consistency, confirmatory factor analysis, and parsimony results in endorsement of the four-factor solution for the PCS for this sample. (SLD)

This investigation was conducted to validate the Beck Depression Inventory--II (BDI-II; A. T. Beck, R. A. Steer, & G. K. Brown, 1996) in samples of adolescent psychiatric inpatients. The sample in each substudy was primarily Caucasian. In Study 1, expert raters (N=7) and adolescent psychiatric inpatients (N=13) evaluated the BDI-II items to assess…

Accumulating evidence suggests that anxiety sensitivity (fear of arousal-related sensations) plays an important role in many clinical conditions, particularly anxiety disorders. Research has increasingly focused on how the basic dimensions of anxiety sensitivity are related to various forms of psychopathology. Such work has been hampered because…

Two instruments, one a self-report measure and one an informant assessment, were developed to assess the strength of a person's end goals and motivational sensitivities. Results of seven studies involving 2548 adults and adolescents support a 15-factor solution for each instrument, with solutions similar to each other. Implications for a model of…

In the present study, the psychometric properties of the German version of the Posttraumatic Diagnostic Scale (PTDS; A. Ehlers, R. Steil, H. Winter, & E. B. Foa, 1996) were evaluated in a sample of 143 trauma survivors. To investigate convergent and discriminant validity of this questionnaire, the authors assessed posttraumatic stress disorder…

Four studies on the psychometric properties of the Coping Inventory for Stressful Situations (CISS), involving 682 adults and 1,592 college students, investigated factor structure and construct and content validities. Overall, results suggest that the CISS is a valid and reliable measure of basic coping styles. (SLD)
