AbstractThis study reports on the validity of the 15-item Portuguese version of the Systemic Clinical Outcome Routine Evaluation (SCORE-15; Vilaça, Silva, & Relvas, 2014), a brief and comprehensive measure of family functioning. Previous studies with SCORE-15 show that this version replicates the three-factor solution found for the original English version: Family strengths, Family communication and Family difficulties. In addition to reviewing previous studies, this article analyses the discriminant, convergent and predictive validity of the Portuguese SCORE-15. To do so, the SCORE-15 was administered to family members attending systemic family or couple’s therapy at the start of the first and fourth sessions and also to a group of non-clinical individuals. Overall, data are reported from 618 participants, including 136 from families attending systemic therapy and 482 community family members. Comparisons of community and clinical samples (discriminant validity) showed statistically significant differences for the total scale and subscales (p < .001), with the community participants presenting healthier family functioning than the clinical ones. Analyses using SCORE-15 and the Quality of Life – adult version, another family measure applied simultaneously (convergent validity), indicate that both scales are significantly (p < .01) and moderately (r = –.47) correlated. Mean score analysis of SCORE-15’s therapeutic sensitivity to change (predictive validity) showed that only the Family communication subscale was sensitive to statistically significant improvement (p < .05) from session 1 to session 4, whereas the SCORE-15’s reliability change index points to its ability to detect clinical improvements (RCI = 14%).

Abstract Background Sensorimotor abnormalities precede and predict the onset of psychosis. Despite the practical utility of sensorimotor abnormalities for early identification, prediction, and individualized medicine applications, there is currently no dedicated self-report instrument designed to capture these important behaviors. The current study assessed and validated a questionnaire designed for use in individuals at clinical high-risk for psychosis (CHR). Methods The current study included both exploratory (n = 3009) and validation (n = 439) analytic datasets—that included individuals identified as meeting criteria for a CHR syndrome (n = 84)—who completed the novel Sensorimotor Abnormalities and Psychosis-Risk (SMAP-R) Scale, clinical interviews and a finger-tapping task. The structure of the scale and reliability of items were consistent across 2 analytic datasets. The resulting scales were assessed for discriminant validity across CHR, community sample non-psychiatric volunteer, and clinical groups. Results The scale showed a consistent structure across 2 analytic datasets subscale structure. The resultant subscale structure was consistent with conceptual models of sensorimotor pathology in psychosis (coordination and dyskinesia) in both the exploratory and the validation analytic dataset. Further, these subscales showed discriminant, predictive, and convergent validity. The sensorimotor abnormality scales discriminated CHR from community sample non-psychiatric controls and clinical samples. Finally, these subscales predicted to risk calculator scores and showed convergent validity with sensorimotor performance on a finger-tapping task. Conclusion The SMAP-R scale demonstrated good internal, discriminant, predictive, and convergent validity, and subscales mapped on to conceptually relevant sensorimotor circuits. Features of the scale may facilitate widespread incorporation of sensorimotor screening into psychosis-risk research and practice.

Abstract. Desire thinking refers to verbal and imaginal elaboration of a desired target. It predicts escalations in craving intensity and subsequent alcohol use. This article aimed to determine the psychometric properties of the Dutch version of the Desire Thinking Questionnaire (DTQ-D). In Study 1, a confirmatory factor analysis provided support for the original two-factor solution, achieved with adequate internal consistency. The DTQ-D demonstrated partial invariance over time. In Study 2, convergent validity with measures of craving was demonstrated. Discriminant validity with measures of severity of alcohol use and perseverative thinking was satisfactory. Concurrent validity was established by comparing three distinctive groups of alcohol users with increasing levels of drinking: a normative and an out- and in-patient sample. The normative group scored significantly lower on the DTQ-D than the clinical groups. Within the normative sample a low and higher at-risk drinking group could be distinguished. Overall, the DTQ-D possesses reasonable psychometric properties for use with alcohol-drinking samples. However, additional psychometric evaluation in larger clinical samples as well as in other addictions is warranted.

Collective Empowerment

Background The role of online health communities (OHCs) in patient empowerment is growing and has been increasingly studied in recent years. Research has focused primarily on individualistic conception of patients’ empowerment, with much less attention paid to the role of OHCs in the development of patients’ collective empowerment. Although OHCs have immense potential for empowerment that goes beyond the individual, the concept and scale of collective empowerment in OHCs have not yet been developed or validated. Objective This study aimed to develop an instrument for measuring collective empowerment in online health communities (CE-OHC) and to test its quality by investigating its factorial structure, reliability, construct validity, and predictive validity. Methods The CE-OHC scale was developed according to a strict methodology for developing valid and reliable scales. An initial set of 20 items was first tested in the pilot study conducted in 2016 using a sample of 280 registered users of Slovenia’s largest OHC. A refined version with 11 items was tested in the main study conducted in 2018 on a random sample of 30,000 registered users of the same OHC. The final sample comprised 784 users. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to investigate the factorial structure, discriminant validity, and convergent validity of the scale. Cronbach alpha coefficient was used to determine the CE-OHC scale’s internal consistency. To establish the predictive validity, ordinary least squares regression was performed to test the role of CE-OHC in users’ civic participation. Results The EFA resulted in a two-factor solution, and the two factors—knowledge of resources and resource mobilization for collective action—together explain 63.8% of the variance. The second-order CFA demonstrated a good fit to the data (root mean square error of approximation=0.07) and the scale had a good internal consistency (alpha=.86). Although evidence of the scale’s convergent validity was partially provided, discriminant validity of the scale remained unconfirmed. Overall, CE-OHC was confirmed to be a predictor of users’ civic participation, but the influence was somewhat weak and inconsistent across two subscales. Conclusions The proposed CE-OHC scale is a reliable and relatively valid instrument and serves as a good baseline to advance the measurement of collective empowerment in OHC contexts. This is the first scale developed for this purpose, and future research should focus on the development of a clear nomological network of the collective empowerment construct in relation to the OHC settings.

The convergent, discriminant, and predictive validity of the tripartite model of attitudes is investigated. On the basis of a structural equation methodology, evidence is obtained for convergent validity. Moreover, a factor analysis of the attitude measures and measures of perceived extraneous events and personal and social normative beliefs provides evidence for discriminant validity. Finally, evidence for predictive validity based on actual and intended behaviors is found to be mixed. The implications of these findings for research pertaining to the prediction of consumer behavior are discussed.

Scale Data

Previous research suggests that individuals vary in their proclivity to purchase products on impulse. This paper presents the results of four studies (Study 1, n = 212; Study 2, n = 152; Study 3, n = 124; and Study 4, n = 550) designed to develop and validate the Impulse Buying Tendency Scale. Data from the first three studies indicate that the scale is unidimensional and internally consistent. The third study provides evidence supporting convergent validity and discriminant validity and the fourth of predictive validity.

Mastery behaviours — seeking out challenging tasks and continuing to work on them despite difficulties — are integral to achievement but difficult to measure with precision. The current study reports on the development and validation of the computer-based persistence, effort, resilience, and challenge-seeking (PERC) task in two demographically diverse samples of adolescents (total N = 3,188). We present evidence for convergent validity with self-reported mastery behaviours and learning mindsets, discriminant validity from theoretically unrelated constructs, and incremental predictive validity for grade point average (GPA). Results suggest that the PERC task may be a useful tool for assessing mastery behaviours at scale.

The impact of the COVID-19 pandemic on students’ personal, academic, and social life has been quite stressful. The threat to life from the virus, social isolation, and the need to shift from face-to-face learning to online mode has been challenging. Thus, the purpose of the present study was to develop and validate a self-administered tool to assess the source of COVID-19 pandemic stress among college students. The data was collected online using google forms in two phases. The data collected from 173 participants from phase one was analyzed using exploratory factor analysis (EFA). The second phase data of 216 participants were analyzed to validate the factor structure using confirmatory factor analysis (CFA). The standardized factor loadings, Composite Reliability (CR), and AVE of factors were assessed to determine the convergent validity of the scale. Similarly, discriminant validity and concurrent predictive validity were assessed through the HTMT ratio of correlations and ROC curves, respectively. A succession of Exploratory Factor Analysis yielded a five-factor solution, explaining 73.83 percent variance with 13 indices. CFA via maximum likelihood with bootstrapping indicated a good fit for the five-factor model (SRMR = 0.037, RMSEA = 0.049, CFI = 0.981). The standardized factor loadings, Composite Reliability (CR), and AVE of factors together suggest acceptable convergent validity. Further, the ROC curve results to assess stress indicated an acceptable AUC, with a magnitude of 0.79, p < 0.01, indicating concurrent predictive validity for the five-factor Student COVID-19 Stress Scale (SCSS). HTMT ratio of correlations <0.85 indicated discriminant validity for the factor structure. The CR > 0.70 for the dimensions indicated acceptable reliability. Thus, the SCSS can be an effective instrument to assess the source of pandemic stress among students so that tailor-made timely interventions can be provided to prevent long-term adverse effects.
