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 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 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 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.     

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.     

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 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.     

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 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).     

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.     

Construction and initial validation of the Work Context Inventory

Although the importance of taking the work context into account is now a given when attempting to better understand behavior at work and career development, it is not always effectively considered, and a consensus regarding this context is difficult to reach. Using both qualitative and quantitative methods, the present study developed the Work Context Inventory, composed of 36 items drawn from analyses of work situations. The inventory describes 9 dimensions related to empowerment, relationships with others at work, and performance requirements. The study discusses this theoretical and empirical model by comparing it with other models that were based on different conceptual and methodological approaches. Finally, we present the practical implications of using this model, such as to support career mobility or skill development.     

Further validation of the Iowa Sleep Disturbances Inventory

This study examined the reliability and validity of an expanded version of the Iowa Sleep Disturbances Inventory (ISDI; Koffel & Watson, 2010) in 2 samples (219 college students and 200 psychiatric patients). The expanded ISDI includes the scales Sleep Paralysis and Sleep Hallucinations. These scales, along with the Nightmares scale, help define a higher order factor entitled Unusual Sleep Experiences. This factor was distinct from the Insomnia and Lassitude factors that were reported previously. The expanded ISDI showed strong evidence of convergent and discriminant validity with the corresponding interview ratings on a clinician rating version of the ISDI. Mean convergent correlations were .68 in students and .70 in patients. Convergent correlations were significantly higher than discriminant correlations in 99.8% of the 624 comparisons. This study also reports the associations of higher order sleep factors with questionnaire and interview measures of pathological symptoms (e.g., depression, anxiety, dissociation, and schizotypy). The Lassitude factor was specific to dysphoria, whereas the Unusual Sleep Experiences factor was specific to posttraumatic stress disorder (PTSD) and dissociation. Finally, several ISDI scales showed strong evidence of specificity in relation to pathological symptoms; in particular, there were strong associations between (a) ISDI Fatigue and measures of dysphoria, (b) ISDI Nightmares and measures of PTSD, and (c) ISDI Sleep Hallucinations and measures of dissociation.     

Construct validation of the Bern Sex Role Inventory

The purpose of this study was to assess the construct validity of the Bern Sex Role Inventory (BSRI), a questionnaire which measures pyschological androgyny. Psychological androgyny refers to the fact that a person may possess both traits traditionally considered feminine, and traits traditionlly considered masculine, i.e. that femininity and masculinity are two independent dimensions. Eight different groups, chosen because their androgyny scores were expected to differ, participated in the study. The groups differed as expected and this is taken as an evidence that the BSRI has construct validity and that it is valid for Swedish conditions.     

Development and preliminary validation of the body satisfaction scale (BSS)

Abstract

This paper describes the development of a simple paper-and-pencil test designed to measure satisfaction/dissatisfaction with 16 body parts. It is based on the body-cathexis scale of Secord and Jourard (1953) but takes only 2–3 minutes to complete. The factorial structure of the scale is described together with the three summative scales (“general,” “head parts” and “body parts” dissatisfaction) which are derived. The internal consistency of the scales was found to be acceptable. Significant positive correlations are also reported with the Body Shape Questionnaire (Cooper et al., 1987). The paper reports data for female comparison groups (college students, nursing students and female volunteers) and for samples of eating disorder patients and overweight subjects. The latter two groups report significantly higher body dissatisfaction than the comparison groups. Finally, it is argued that the scale is useful for work in health related fields and some current applications are briefly described.     

Development and validation of the Stephenson Multigroup Acculturation Scale (SMAS)

This article describes the development and psychometric evaluation of the Stephenson Multigroup Acculturation Scale (SMAS). Three studies were conducted to describe its development and refinement, examine its psychometric properties with 436 participants from 5 ethnic groups, and examine the robustness of the factor structure with a new sample. Exploratory factor analyses generated a 2-factor solution: ethnic society immersion and dominant society immersion. Item refinement resulted in a 32-item version of the SMAS. Findings indicated a robust factor structure across groups. Confirmatory factor analysis indicated that the 2-factor model provided a close approximation to the observed data. Studies indicated high reliability and validity indexes. Findings support the role of acculturation as a mediator between ethnic group affiliation and standardized assessment results.     

Development and validation of a Spanish version of the Athletic Coping Skills Inventory, ACSI-28

This study involved the translation, cultural adaptation and validation of the Athletic Coping Skills Inventory (ACSI-28) for a Spanish-speaking sport environment. The sample was made up of 1,253 Spanish athletes, 967 males and 286 females. Confirmatory factor analysis (CFA) showed that the 7-factor structure found in the English version was replicated in the Spanish translation in both males and females. Likewise, the reliability coefficients were similar to those of the English version, with values exceeding .80 for the total score. Several of the subscales correlated positively with sports experience and performance level. The Spanish version of the ACSI-28 thus maintains the factor structure of the original and exhibits similar psychometric properties. Consequently, it can reliably be applied to Spanish-speaking athletes for research and evaluation purposes.     

Clinical validation of the Chinese Personality Assessment Inventory

The clinical validity of the Chinese Personality Assessment Inventory (CPAI; F. M. Cheung, K. Leung, et al., 1996) was examined in 2 studies involving a group of 167 male prisoners in Hong Kong and a group of 339 psychiatric patients in China. Elevated scores on the clinical scales were obtained for the clinical samples. Logistic regression analyses confirmed that the CPAI scales were useful in differentiating between male prisoner and the Hong Kong male normative sample and between psychiatric patients and a random sample of normal adults in China. Multivariate analyses of variance results showed significant differences on the CPAI clinical scales and personality scales among subgroups of psychiatric patients with diagnoses of bipolar, schizophrenic, and neurotic disorders. The usefulness of an indigenous personality inventory is discussed.
