We explicated the validity of the Inventory of Depression and Anxiety Symptoms (IDAS; Watson et al., 2007) in two samples (306 college students, and 605 psychiatric patients). The IDAS scales showed strong convergent validity in relation to parallel interview-based scores on the Clinician Rating version of the IDAS (IDAS-CR); the mean convergent correlations were .51 and .62 in the student and patient samples, respectively. With the exception of Well-Being, the scales also consistently demonstrated significant discriminant validity. Furthermore, the scales displayed substantial criterion validity in relation to DSM-IV mood and anxiety disorder diagnoses in the patient sample. We identified particularly clear and strong associations between (a) major depression and the IDAS General Depression, Dysphoria and Well-Being scales; (b) panic disorder and IDAS Panic; (c) posttraumatic stress disorder and IDAS Traumatic Intrusions; and (d) social phobia and IDAS Social Anxiety. Finally, in logistic regression analyses, the IDAS scales showed significant incremental validity in predicting several DSM-IV diagnoses when compared against the Beck Depression Inventory-II (Beck, Steer, & Brown, 1996) and Beck Anxiety Inventory (Beck & Steer, 1990).

Specific Symptom

We describe a new self-report instrument, the Inventory of Depression and Anxiety Symptoms (IDAS), which was designed to assess specific symptom dimensions related to major depression and related anxiety disorders. We created the IDAS by conducting principal factor analyses in three large samples (college students, psychiatric patients, community adults); we also examined the robustness of its psychometric properties in five additional samples (high school students, college students, young adults, postpartum women, psychiatric patients) that 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 two 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.

The Flourishing Scale (FS), created by Diener et al., is a brief subjective perception measurement which assesses flourishing and provides a single score across 8 items. The aim of this study was to assess the psychometric properties of the Spanish version of the FS. Participants were 1,502 university students from different faculties and fields of knowledge. The results reveal good internal consistency. The single factor structure of the FS was supported by the multigroup confirmatory factor analysis, which also provided evidence of the invariant structure of the scale across two subsamples. The scale’s convergent validity with another measure of psychological well-being and its discriminant validity with the depression, anxiety, and stress symptom scale were demonstrated through the significant correlations observed with said measures. The FS was found to be apt for use in evaluating general well-being in the Spanish population and may be considered a reliable measure in future well-being studies. It can also be used as an instrument for planning, executing, and/or assessing practical interventions in social, care, and health-related programs.

Communication and communication behaviors in situational contexts are essential conditions for well-being and quality of life in people with dementia. Measuring methods, however, are limited. The CODEM instrument, a standardized observational communication behavior assessment tool, was developed and evaluated on the basis of the current state of research in dementia care and social-communicative behavior. Initially, interrater reliability was examined by means of videoratings (N = 10 people with dementia). Thereupon, six caregivers in six German nursing homes observed 69 residents suffering from dementia and used CODEM to rate their communication behavior. The interrater reliability of CODEM was excellent (mean κ = .79; intraclass correlation = .91). Statistical analysis indicated that CODEM had excellent internal consistency (Cronbach’s α = .95). CODEM also showed excellent convergent validity (Pearson’s R = .88) as well as discriminant validity (Pearson’s R = .63). Confirmatory factor analysis verified the two-factor solution of verbal/content aspects and nonverbal/relationship aspects. With regard to the severity of the disease, the content and relational aspects of communication exhibited different trends. CODEM proved to be a reliable, valid, and sensitive assessment tool for examining communication behavior in the field of dementia. CODEM also provides researchers a feasible examination tool for measuring effects of psychosocial intervention studies that strive to improve communication behavior and well-being in dementia.

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 of 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 factors of Insomnia and Lassitude 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.

ABSTRACTBackground:Although rates of anxiety tend to decrease across late life, rates of anxiety increase among a subset of older adults, those with mild cognitive impairment (MCI) or dementia. Our understanding of anxiety in dementia is limited, in part, by a lack of anxiety measures designed for use with this population. This study sought to address limitations of the literature by developing a new measure of anxiety for cognitively impaired individuals, the anxiety in cognitive impairment and dementia (ACID) Scales, which includes both proxy (ACID-PR) and self-report (ACID-SR) versions.Methods:The ACID-SR and ACID-PR were administered to 45 residents, aged 60 years and older, of three long-term care (LTC) facilities, and 38 professional caregivers at these facilities. Other measures of anxiety, and measures of depression, functional ability, cognition, and general physical and mental health were also administered.Results:Initial evaluation of its psychometric properties revealed adequate to good internal consistency for the ACID-PR and ACID-SR. Evidence for convergent validity of measures obtained with the ACID-SR and ACID-PR was demonstrated by moderate-to-strong associations with measures of worry, depressive symptoms, and general mental health. Discriminant validity of measures obtained with the ACID-SR and ACID-PR was demonstrated by weak correlations with measures of cognition, functional ability, and general physical well-being.Conclusions:The preliminary results suggest that the ACID-SR and ACID-PR can obtain reliable and valid measures of anxiety among individuals with cognitive impairment. Given the subjective nature of anxiety, it may be prudent to collect self-report of anxiety symptoms even among those with moderate cognitive impairment.

AbstractBackgroundPersonality traits are important factors with regard to the tendency to experience and response to stress. This study introduces and tests a new stress-related personality scale called the Virtual Inventory of Behavior and Emotions (VIBE).MethodsTwo samples totaling 5512 individuals (with 66% between the ages of 18 and 34) completed the VIBE along with other measures of personality, stress, mood, and well-being. Results: Exploratory factor analyses revealed a four-factor structure for the instrument with dimensions labelled: 1) stressed; 2) energetic; 3) social; and 4) disciplined. Confirmatory factor analytic procedures on the final 23-item version showed good psychometric properties and data fit while machine learning analyses demonstrated the VIBE’s ability to distinguish between groups with similar patterns of response. Strong convergent validity was suggested through robust correlations between the dimensions of the VIBE and other established rating scales.ConclusionOverall, the data suggest that the VIBE is a promising tool to help advance understanding of the relations between stress, personality, and related constructs.

Symptom Measures

This chapter reviews the convergent, discriminant, criterion, and incremental validity of symptoms of the DSM-5 anxiety disorders; these include panic disorder, agoraphobia, social anxiety disorder/social phobia, specific phobia, and generalized anxiety disorder (GAD). Symptom measures of social anxiety/social phobia, panic disorder, claustrophobia, and GAD generally displayed impressive construct validity in these data. Specifically, they tended to show strong convergent validity and significant discriminant validity across both self-report and interview-based measures; moreover, they displayed substantial criterion validity and impressive incremental validity in relation to conceptually linked DSM diagnoses. One problem, however, is that they generally showed poor diagnostic specificity; that is, although they correlated substantially with their target diagnoses, they often displayed equally strong relations with at least some other internalizing disorders. In contrast, self-report measures of agoraphobia and specific phobia (particularly the latter) generally exhibited unimpressive criterion and incremental validity in these analyses.

This chapter explores the nature of positive emotional disturbance across various disorders. It reviews findings based on the positive affect scales of the Expanded Form of the Inventory of Depression and Anxiety Symptoms (IDAS-II), the Clinician Rating version of the IDAS (IDAS-CR), and the Expanded Form of the Positive and Negative Affect Schedule (PANAS-X). These data reveal that IDAS-II Well-Being, IDAS-CR Well-Being, and PANAS-X Joviality assess a highly adaptive form of positive affect. These measures show particularly strong negative associations with symptoms and diagnoses of depression; they also are negatively related to social anxiety and to the negative symptoms (aloofness, restricted affectivity) of psychosis. In contrast, IDAS-II Euphoria and PANAS-X Self-Assurance tap a more dysfunctional form of positive affect. These scales correlate positively with many forms of psychopathology, including mania, narcissism, histrionic personality disorder, and the positive symptoms of psychosis (e.g., eccentricity, unusual beliefs and experiences).

Two Samples

A multitrait-multimethod analysis was performed on instructors' ratings obtained from three formats, behaviorally anchored rating scales, graphic rating scale, and mixed standard scale, for two samples of 100 undergraduate students each. The two samples were distinguished on the basis of whether the statements on the mixed-standard scale were behaviorally specific or more generic descriptions of the dimensions. The more specific mixed-standard scale yielded a greater proportion of inconsistent ratings than the less specific one. Also, convergent and discriminant validity were smaller and method variance and unexplained error were greater for the more specific mixed-standard scale. However, a more detailed examination of these effects in terms of selected average correlations indicated that some of these results were not necessarily due to the format. Relative levels of convergent validity were higher and relative levels of discriminant validity were lower than found by Dickinson and Zellinger in 1980 for faculty ratings in a professional school. Over-all, the mixed-standard scale engendered as much convergent and discriminant validity as did the other two rating formats.

High Internal Consistency

Though often cited, Erikson's theory has been relatively neglected in empirical studies of adult development, partly because few measures operationalize his psychosocial constructs. The present research examined the internal consistency and construct validity of an expanded version of the Inventory of Psychosocial Development (E-IPD) which included the generativity and ego integrity scales created by Boylin et al. [1]. Participants were seventy-nine adults with a mean age of forty-two and mean educational level of fifteen years. Total E-IPD scores were found to have high internal consistency but many individual stage scales did not. Men's E-IPD scores showed discriminant validity with respect to social desirability and women's E-IPD scores showed convergent validity with a measure of subjective well-being. Psychosocial development scores were largely unrelated to age, indicating that the E-IPD may have little validity as a measure of adult development.
