Development and validation of the Inventory of Depression and Anxiety Symptoms (IDAS)

The authors describe a new self-report instrument, the Inventory of Depression and Anxiety Symptoms (IDAS), which was designed to assess specific symptom dimensions of major depression and related anxiety disorders. They created the IDAS by conducting principal factor analyses in 3 large samples (college students, psychiatric patients, community adults); the authors also examined the robustness of its psychometric properties in 5 additional samples (high school students, college students, young adults, postpartum women, psychiatric patients) who were not involved in the scale development process. The IDAS contains 10 specific symptom scales: Suicidality, Lassitude, Insomnia, Appetite Loss, Appetite Gain, Ill Temper, Well-Being, Panic, Social Anxiety, and Traumatic Intrusions. It also includes 2 broader scales: General Depression (which contains items overlapping with several other IDAS scales) and Dysphoria (which does not). The scales (a) are internally consistent, (b) capture the target dimensions well, and (c) define a single underlying factor. They show strong short-term stability and display excellent convergent validity and good discriminant validity in relation to other self-report and interview-based measures of depression and anxiety.     

Development and validation of a Dutch translation of the Big Five Inventory (BFI)

In this article, we describe the translation and validation of the Dutch Big Five Inventory (BFI; John & Srivastava, 1999), a short instrument designed to measure the Big Five factors of personality. We obtained evidence of the instrument's good psychometric properties in terms of factorial equivalence to the English original and other BFI translations and the relative independence and internal consistency of the five scales. The findings suggest that the instrument can be used in diverse age groups without substantial changes in factor structure. The Dutch BFI scales showed similar demographic correlates as the English original, with higher Agreeableness and Conscientiousness and lower Neuroticism values in older participants, higher Neuroticism values in women, and higher Openness and Conscientiousness values in better educated participants. Use of the Dutch BFI will allow researchers to integrate their findings with the extant Big Five research literature. The brevity of the instrument will be appealing to researchers who are concerned about taxing the time and motivation of their participants.     

Development and validation of the Delaying Gratification Inventory

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 behavior, involving food, physical pleasures, social interactions, money, and achievement, no published measure to date has tapped all 5 components of the content domain. Existing measures have been criticized for limitations related to efficiency, reliability, and construct validity. Using an innovative Internet-mediated approach to survey construction, we developed the 35-item 5-factor Delaying Gratification Inventory (DGI). Evidence from 4 studies and a large, diverse sample of respondents (N = 10,741) provided support for the psychometric properties of the measure. Specifically, scores on the DGI demonstrated strong internal consistency and test-retest reliability for the 35-item composite, each of the 5 domains, and a 10-item short form. The 5-factor structure fit the data well and had good measurement invariance across subgroups. Construct validity was supported by correlations with scores on closely related self-control measures, behavioral ratings, Big Five personality trait measures, and measures of adjustment and psychopathology, including those on the Minnesota Multiphasic Personality Inventory-2-Restructured Form. DGI scores also showed incremental validity in accounting for well-being and health-related variables. The present investigation holds implications for improving public health, accelerating future research on gratification delay, and facilitating survey construction research more generally by demonstrating the suitability of an Internet-mediated strategy.     

Development and validation of the Eating Behavior Inventory

The Eating Behavior Inventory (EBI) is a self-report instrument for assessing behaviors that have been theoretically implicated in weight loss, e.g., self-monitoring of food intake and of weight, refusing offers of food, eating at only one place, shopping from a list, eating in response to emotions. Thirty items were constructed in the form of first-person statements, e.g., I eat in the middle of the night. Each item was to be rated with a 5-point scale according to how often it was true for the respondent. Items were scored such that higher scores always reflected more appropriate (theoretically facilitative of weight control) eating patterns. Validity of individual items and total score was assessed in four studies. Twenty-six of the original items appeared valid and were retained. The resulting total score demonstrated validity in these studies and in two cross-validational comparisons. Internal consistency as measured by split-half reliability and correlations of item scores with total score was acceptable. One month test-retest reliability of item and total scores was satisfactory. Clinical and research applications of the EBI are discussed.An early version of this article was presented at the Taos International Conference on Treatment of Addictive Behaviors, Taos, New Mexico, February 1979.     

Development and validation of the Illness Behavior Inventory

The development and validation of a measure of illness behavior are presented. From a large domain sample of illness-related behaviors, a 20-item self-report measure was developed, the Illness Behavior Inventory (IBI). Validation data are presented from a series of independent studies with healthy and chronically ill individuals. Results indicate that the IBI possesses acceptable levels of internal consistency, test-retest reliability, structural reliability, discriminant validity, concurrent validity, and predictive validity. The applicability of the IBI to various areas of inquiry in behavioral medicine research and practice is discussed and directions for future research are outlined.     

Development and validation of the Self-Identity Inventory (SII): a multicultural identity development instrument

The Self-Identity Inventory (SII) was developed using the Optimal Theory Applied to Identity Development (OTAID) model. A sample of 325 culturally diverse respondents completed the SII, the Tolerance Scale from the California Psychological Inventory, the Belief Systems Analysis Scale, and the Social Desirability and Infrequency Scales. Through confirmatory factor analysis, goodness-of-fit, and social desirability/item infrequency measures, SII items were analyzed, resulting in a 6-scale, 71-item inventory. Internal consistency for the scales ranged from .72 to .90. Test-retest reliability ranged from .72 to .92. Correlations with external construct validity measures supported predictions. Interscale correlations and other statistical tests primarily supported the OTAID model. Implications for therapy and future research are suggested.     

Development and validation of discriminant functions for the Strong Interest Inventory

This study compared the relative accuracy of (a) single Occupational Scale (OS) scores on the Strong Interest Inventory (SII) and (b) multiple-predictor scoring functions for discriminating members of nine occupations from people-in-general. The functions were constructed using discriminant function analysis with 4797 adults drawn from criterion samples for the 1985 SII. The analyses included Basic Interest Scale (BIS) scores only or combinations of OSs and BISs. Two subsequent analyses, one of which was cross-validation using 1302 young adults with little work experience, also were conducted. Results indicated that BIS-only functions yielded hit rates comparable to single OSs, and functions that combined OSs and BISs generally produced slight improvements in accuracy. These findings are potentially relevant for future SII scale development decisions.     

Development and validation of the Childhood Perfectionism Inventory (I.P.I.)

There are a few studies linking children's perfectionism with diverse internalized or externalized disorders. Likewise, in Spanish, there is no scale that measures the diverse aspects that comprise it. This paper presents the Children's Perfectionism Inventory (IPI). The sample comprised 2,260 participants (51.2% males and 48.8% females). The age range is between 8 and 13 years (mean= 9.94 and SD= 1.27). Sampling was stratified and random. Of the sample, 78.1% are from public education and 21.9% from private education. 16.2% reside in rural areas and 83.8% in urban areas. To study the validity of the questionnaire, cross-validation was performed. Initially three factors were obtained through exploratory factor analysis: Self-assessment, Self-imposed and External Pressures, with adequate reliability indices (Cronbach's alpha= .89, .87 and .88, respectively). Subsequently, using a confirmatory method, it was found that the three initial factors were explained by a single second-order factor called Perfectionism.     

The development and validation of the Beliefs About Losing Control Inventory (BALCI)

ABSTRACT

Cognitive theory of obsessive-compulsive disorder (OCD) proposes that maladaptive beliefs play a pivotal role in the development and maintenance of symptoms. Clinical reports as well as recent psychometric and experimental investigations suggest that control-related beliefs in OCD may benefit from expansion to include aspects of losing control. However, currently available measures either focus on other facets of control (e.g., sense of control) or do not put emphasis on beliefs about losing control (e.g., beliefs about control over thoughts). The current study aimed to develop and validate the Beliefs About Losing Control Inventory (BALCI), a self-report measure of negative beliefs about losing control, in a sample of undergraduate participants (N= 488). An exploratory factor analysis revealed that the BALCI’s 21 items capture negative beliefs about losing control over one’s thoughts, behaviour, and emotions (Factor 1), beliefs about the importance of staying in control (Factor 2), and beliefs about losing control over one’s body/bodily functions (Factor 3). The BALCI was also found to have good convergent and divergent validity and to be associated with elevated OCD symptoms above and beyond previously identified obsessive beliefs. Theoretical implications and recommendations for the field of cognitive-behaviour therapy are discussed.     

Elaboration and validation of the athletes Idiocentric and Allocentric Profile Inventory (I-A Profile)

The athlete's psychological profile is one of the most studied areas in sport psychology, but there is no consensus in this area. The purpose of this study was to elaborate and validate a scale to measure and classify athletes into a Idiocentric-Alocentric profile. The method was split in two phases: a) Items elaboration and theoretical model and b) Validation. Qualitative analyses were performed during the first phase and factorial analysis and Cronbach's Alpha were used to validate the instrument. The final instrument was composed by 27 items and the factorial structure showed three factors for Idiocentrism (Self-Realization & Competitiveness, Hedonism, Team Emotional Distance and a second order factor - Idiocentrism Level) and one factor for the Alocentrism (Alocentrism Level). It was concluded that the pattern and consistency of the results indicate that this inventory could be used as a reliable research tool in Brazilian sports context.     

Development and initial validation of validity scales for the NEO-Five Factor Inventory

Based upon the methodology established by Schinka, Kinder, and Kremer (Schinka, J. A., Kinder, B. N., & Kremer, T. (1997). Research validity scales for the NEO-PI-R: Development and initial validation. Journal of Personality Assessment, 68, 127–138), a set of validity scales were developed for the NEO-Five Factor Inventory (NEO-FFI, Costa, P. T., & McCrae, R. R. (1992). Revised NEO Personality Inventory and NEO Five Factor Inventory Professional Manual. Odessa, FL: Psychological Assessment Resources). In Study 1, 111 undergraduates completed the NEO-FFI and item means, standard deviations, and intercorrelations were used to construct measures of Positive Impression Management, Negative Impression Management, and Inconsistent Responding. In Study 2, 146 participants completed the NEO-FFI under one of five instructional sets (control, fake good, fake bad, graduate psychology and police academy admissions). A set of randomly produced NEO-FFI profiles were added to this data set. ANOVA results provided support for the utility of the validity scales, as they were differentially sensitive to random responding, positive and negative impression management in hypothesized ways.     

Development and validation of the trait and state versions of the Post-Event Processing Inventory

Background: Post-event processing (PEP) refers to negative and prolonged rumination following anxiety-provoking social situations. Although there are scales to assess PEP, they are situation-specific, some targeting only public-speaking situations. Furthermore, there are no trait measures to assess the tendency to engage in PEP. Objectives: The purpose of this research was to create a new measure of PEP, the Post-Event Processing Inventory (PEPI), which can be employed following all types of social situations and includes both trait and state forms. Design and method: Over two studies (study 1, N?=?220; study 2, N?=?199), we explored and confirmed the factor structure of the scale with student samples. Results: For each form of the scale, we found and confirmed that a higher-order, general PEP factor could be inferred from three sub-domains (intensity, frequency, and self-judgment). We also found preliminary evidence for the convergent, concurrent, discriminant/divergent, incremental, and predictive validity for each version of the scale. Both forms of the scale demonstrated excellent internal consistency and the trait form had excellent two-week test–retest reliability. Conclusion: Given the utility and versatility of the scale, the PEPI may provide a useful alternative to existing measures of PEP and rumination.     

Feeling safe at work: Development and validation of the Psychological Safety Inventory

Psychological safety, defined as perceptions that an individual within a team is supported and feels safe to take interpersonal risks, voice opinions, and share ideas, is vital for organizational effectiveness. However, there is no consensus on how workplace psychological safety should be measured. We developed the Psychological Safety Inventory (PSI) in response to organizational needs to accurately assess psychological safety. A 70-item version of the PSI was administered to 497 employees from Canada, the United States, and the United Kingdom. Based on factor analytic findings, we reduced the preliminary PSI to a 30-item, five-factor scale. The PSI showed high reliability and correlated as anticipated with convergent measures. Overall, the PSI is a valid and reliable measure of workplace psychological safety.     

Development and validation of a measure for emotion regulation at work: Introducing the Workplace Emotion Regulation Preference Inventory (WERPI)

Emotion regulation preference varies from person to person. However, the emotion regulation literature has mostly dichotomized preference to cognitive change and response modulation. The current investigation focused on development and validation of a comprehensive measure of workplace emotion regulation and examined the relationship between all emotion regulation strategies using a well-known taxonomy (Gross, 1998) and customer service performance. Preliminary evidence supports the validity of the new measure. The four groups identified in this analysis showed significant differences on customer service performance, suggesting that individual differences in regulation preference may be important to consider. Theoretical and practical implications of findings are discussed.     

Development and preliminary validation of the Concise Neuropsychological Screening Inventory (CNSI): A clinical tool for use in psychiatric settings

We describe the development and preliminary validation of the Concise Neuropsychological Screening Inventory (CNSI), designed to afford clinical psychologists working in psychiatric settings a simple, rapid, and objective assessment of 10 vital left- and right-hemisphere brain functions: (1) Receptive and Expressive Language, (2) Orientation, (3) Attention/Concentration/Immediate Memory, (4) Recent Auditory and Visual Memory, (5) Remote Memory, (6) Motor/Sensory/Tactile Functioning, (7) Visual/Spatial/Motor Integration, (8) Academic Functioning, (9) Intellectual Processes, and (10) Judgment and Reasoning. Preliminary findings suggest that the CNSI can discriminate patients diagnosed with organic mental syndrome from patients with various psychiatric disorders, including chronic schizophrenia (i.e., specificity in screening). Moreover, with regard to predicting neuropsychological differences among various diagnostic groups, the CNSI is superior to some of the most commonly employed tests by psychologists in psychiatric settings (e.g., WAIS-R Digit Span, Digit Symbol, and Bender-Gestalt).     

Construction and validation of the Intragroup Marginalization Inventory

This study reports the development and validation of the Intragroup Marginalization Inventory (IMI). The IMI consists of three scales that assess the extent to which an individual perceives interpersonal distancing from family, friends, and ethnic group community members. Intragroup marginalization is defined as the interpersonal distancing that occurs when an acculturating individual is believed to exhibit behaviors, values, and beliefs that are outside the heritage culture's group norms. Intragroup marginalization is based on social identity theory that asserts that groups maintain their identity by the distinctive behaviors of its members. When an acculturating individual displays behaviors or attitudes that differ from the heritage culture group's norms, the group may respond to the threat with social alienation of the transgressor. The results support the IMI's validity via a) content validity in the development of the items, b) construct validity in the selection of the factors based upon an exploratory factor analysis, c) the replicability of the factors based upon a confirmatory factor analysis, and d) discriminant validity through examining the relationship of the factors with other established measures.     

Development and Initial Validation of the Multicultural Personality Inventory (MPI)

Two studies summarize the development and initial validation of the Multicultural Personality Inventory (MPI). In Study 1, the 115-item prototype MPI was administered to 415 university students where exploratory factor analysis resulted in a 70-item, 7-factor model. In Study 2, the 70-item MPI and theoretically related companion instruments were administered to a multisite sample of 576 university students. Confirmatory factory analysis found the 7-factor structure to be a relatively good fit to the data (Comparative Fit Index =.954; root mean square error of approximation =.057), and MPI factors predicted variance in criterion variables above and beyond the variance accounted for by broad personality traits (i.e., Big Five). Study limitations and directions for further validation research are specified.     

French validation of the Twenty-Item Value Inventory

IntroductionPersonal values are important for understanding psychological phenomena by serving as predictors of individuals’ attitudes and behavior. The Twenty-Item Value Inventory (TwIVI, Sandy et al., 2017) was developed to assess values with items from the Portrait Values Questionnaire (PVQ, Schwartz et al., 2001).ObjectiveThe goal of this study was to assess the reliability and validity of the French version of the TwIVI.MethodTwo French-Canadian samples of adults (N1 = 825; N2 = 429) were recruited in order to test the reliability and validity of the TwIVI.ResultsResults revealed that the French version of the TwIVI showed satisfying temporal stability, convergence validity with the PVQ, and concurrent validity with personality traits. Some issues were observed for internal consistency and structural validity, assessed with both multidimensional scaling and exploratory structural equation modeling.ConclusionOverall, these findings partially support the psychometric qualities of the French version of the TwIVI. Implications for theory and research on values are discussed.     

Development and validation of the Zurich Meeting Questionnaire (ZMQ)

Introduction and objectivesResearch highlights the importance of identifying and examining crucial meeting characteristics and procedures. Thus, the aim of the present research is to develop and validate the Zurich Meeting Questionnaire (ZMQ), an instrument that assesses meeting attendees’ perceptions of meeting design characteristics and task- and relational-oriented procedures during the meeting.MethodThree independent samples (n₁ = 474, n₂ = 464, n₃ = 311) were used to test the psychometric properties, factorial structure, criterion validity, and construct validity of the ZMQ.ResultsResults of confirmatory factor analyses confirmed the assumed two-dimensional structure of meeting procedures. Furthermore, the results provided criterion validity evidence regarding meeting satisfaction and perceived meeting effectiveness. Finally, the pattern of correlations with external variables (team climate inventory, psychological safety, and social desirability) provided initial evidence of construct validity.ConclusionThe ZMQ is a short and psychometrically sound measure of meeting design characteristics and procedures during meetings and is suitable for use in organizational research and the evaluation of meetings in practice.
