The "Patient Health Questionnaire (PHQ)" is a screening instrument, designed for time-efficient detection and severity assessment of depression, anxiety, and other syndromes in medical settings. Besides the questions on psychological symptoms, there are items on psychosocial functioning, on stressors and critical life events. However, for the stress items there are no psychometric properties available until now. The present study is thought to investigate item characteristics, internal consistency as well as factorial and construct validity of the stress scale of the PHQ. A representative sample of the general population of Germany was collected by a demography consulting company (USUMA, Berlin). Per random-route procedure, households and members of the households were selected. The sample was representative for the German community regarding age, gender, and education. In this investigation the following questionnaires were administered: PHQ-Stress, Questions on Life Satisfaction Modules (FLZ-M), Type-D Scale-14 (DS14). The sample included N = 2396 participants with mean age of 48.50 (SD = 17.75; range = 14 to 92) and 55.2 % being female. Reliability of the PHQ stress scale was acceptable (ω = 0.776), but some factor loadings were comparatively low. Model fit indices showed mixed results, some indicating unacceptable and some indicating acceptable fit of the 10-item stress scale of the PHQ. Correlations with related constructs demonstrated the scale's convergent validity. The results of this validation study indicate that the PHQ stress scale, which provides a one-dimensional total stress score, is a valid, good practical and reliable self-report instrument for assessing the severity of psychosocial stress. • Reliability of the PHQ stress scale was acceptable (ω = 0.776). • Model fit indices showed mixed results for the 10-item stress scale of the PHQ. • Correlations with related constructs demonstrated the scale's convergent validity.

Misophonia is characterized by intense emotional reactions to specific sounds or visual stimuli and typically onsets during childhood. An obstacle for research and clinical practice is that no comprehensively evaluated measures for pediatric misophonia exist. In a sample of 102 youth meeting the proposed diagnostic criteria of misophonia, we evaluated the child and parent-proxy versions of the self-reported Misophonia Assessment Questionnaire (MAQ; assessing broad aspects of misophonia) and the child version of the Amsterdam Misophonia Scale (A-MISO-S; assessing misophonia severity). Confirmatory and exploratory factor analysis were used to examine factor structures of the measures. Further, child-parent agreement on the MAQ and associations between both measures and misophonia-related impairment, quality of life, and misophonia-related school interference were examined to evaluate aspects of convergent validity. For both youth- and parent-ratings, four MAQ factors emerged: pessimism, distress, interference, and non-recognition. A-MISO-S showed a unidimensional structure, but the item 'effort to resist' did not load significantly onto the unidimensional factor. Good child-parent agreement on the MAQ scales were found and both MAQ and A-MISO-S were moderately to strongly associated with misophonia-related impairment, quality of life (inverse association), and misophonia-related school interference. MAQ and A-MISO-S assess sensitivity to auditory but not visual stimuli, the sample size was modest, and repeated assessments were not conducted. The combination of MAQ and A-MISO-S shows promise as a multidimensional assessment approach for pediatric misophonia. Future evaluations should include known-groups validity, screening performance, and sensitivity to change in symptom severity. • Misophonia typically onsets during childhood or adolescence. • No validated measures for pediatric misophonia exist • The MAQ and A-MISO-S were evaluated in a sample of 102 youth with misophonia. • The measures show promising psychometric properties. • MAQ and A-MISO-S provide a broad measurement approach to pediatric misophonia.

The Patient Health Questionnaire (PHQ-9) and the Major Depression Inventory (MDI) are psychometric instruments frequently used for depression diagnosis and monitoring in primary care settings. The goal of this study was to assess and compare the construct validity of the PHQ-9 and the MDI using Rasch analysis. The PHQ-9 and the MDI were distributed in random ordering (first or last) to a waiting room sample of Danish primary care patients. Analysis of fit to the Rasch model, ordering of response categories, dimensionality-testing, test for differential item functioning, test for local dependency, and calculation of reliability indices were used to evaluate the psychometric characteristics of the instruments. A sample of 281 persons (18–87 years, 72 % females) responded to both instruments. Reliability was acceptable for PHQ-9 (PSI 0.80) and excellent for MDI (PSI 0.88). Both instruments demonstrated fit to the Rasch model after rescoring of all items. Dimensionality testing supports that both instruments are unidimensional. Indication of local dependency was observed for PHQ-9 item 2&6 and MDI item 1&4. No indication of differential item functioning regarding age, gender or ordering of instruments was found. The PHQ-9 and the MDI both demonstrate measurement problems. Modifying individual items and reducing the number of response categories in both instruments could potentially improve their measurement capabilities. Study findings do not provide a conclusive indication of which instrument has superior operating characteristics. • The PHQ-9 and the MDI are psychometric instruments frequently used for depression diagnosis and monitoring. • The construct validity of the PHQ-9 and MDI was compared head to head using Rasch analysis. • Reliability was excellent for MDI and acceptable for PHQ. • Both instruments demonstrated measurement problems in terms of local dependency of item pairs. • Both instruments may improve by reducing the number of response categories.

Background: The failure to regulate emotions, namely emotional dysregulation (ED), is a relevant construct in adolescent psychiatry, in terms of prognostic and developmental implications. We developed and validated a novel self-report questionnaire for the assessment of ED, the RIPoSt-Y, both in clinical and non-clinical samples.Methods: Items selection and subscales construction were conducted on healthy controls (n=374), while test-retest reliability was evaluated in a subsample (n=72); internal consistency was examined both in the control group and in two clinical samples, respectively including patients with Bipolar Spectrum Disorders (BSD; n=44) and ADHD (n=34). Construct, concurrent and convergent validity were also assessed.Results: Thirty-one items were finally retained, and three subscales were identified (Affective Instability, Emotional Reactivity, Interpersonal Sensitivity). Test-retest was significant for each subscale with moderate-to-good correlations, and internal consistency showed good-to-excellent coefficients. Construct validity was supported by significant differences between patients and controls and gender-related differences. Concurrent validity was confirmed through significant associations with two subscales of the CHT-Q, while convergent validity proved to be significant with the CBCL/YSR dysregulation-profile. Cut-offs were also computed to discriminate clinically significant scores of ED.Limitations: The use of a school-based survey to recruit controls could have biased our results; gender distributions between clinical and non-clinical samples were significantly different.Conclusions: Our novel questionnaire proved to be a valid and reliable tool able to assess the presence of ED in youths and to characterize this fundamental construct in its multidimensional facets.

Background: A number of patient-reported outcomes (PROs) have been developed but insufficient attention has been devoted to the assessment of their clinimetric properties. Clinimetrics, the science of clinical measurements, has been considered an emerging approach for evaluating reliability and validity of PROs. This is the first study using clinimetric principles to compare the construct and criterion validity of the Major Depression Inventory (MDI), the Beck Depression Inventory-II (BDI-II), the World Health Organization Well-Being Index (WHO-5), three of the most widely used PROs for the assessment of depression.Methods: Construct validity was evaluated via Item Response Theory (IRT) models (i.e., combining Rasch and Mokken analyses). Using the ICD-10 diagnostic algorithm for any depression as the gold standard, Receiver Operating Characteristic (ROC) curves were performed to examine the criterion validity of PROs.Results: One hundred healthy subjects (73% females, 32.6 ± 10.5 years) participated in the study, giving a response rate of 90.1%. When using IRT analyses, MDI and WHO-5 were found to be reliable and unidimensional, while BDI-II showed lack of unidimensionality. ROC analyses supported the diagnostic accuracy of MDI and the screening properties of WHO-5.Limitations: The main limitations of the present study are that healthy subjects were assessed only via only self-reported measures and a cross-sectional design was used.Conclusions: WHO-5 and MDI outperformed BDI-II in terms of construct and criterion validity. WHO-5 should be considered when screening for depression, while MDI should be used as a valid diagnostic instrument and as a unidimensional measure to assess depression severity.

Background: The PHQ-2 is a screening test for major depressive disorder (MDD) derived from PHQ-9, which has shown to be useful in the detection of cases of clinical significance in previous studies. The psychometric properties of PHQ-2 in the Colombian population are unknown.Methods: PHQ-2 were assessed in 243 patients in general medical consultations using the Mini-International Neuropsychiatric Interview (MINI) as the gold standard. Internal consistency, convergent validity and criterion validity were calculated by analyzing the Receptor Operating Characteristics (ROC) and the area under the curve (AUC).Results: Cronbach's alpha and McDonald's omega coefficients were 0.71. Spearman's rho coefficients for correlations with PHQ-9 and HADS-D scores were 0.63 and 0.59 (p<0.01). AUC was 0.89. The optimal cut point was ≥2 with the following indicators: sensitivity 0.87 specificity 0.74; Youden index 0.60; PPV 0.47; NPV 0.95; (LR+) 3.24; (LR-) 0.18 (95% CI 0.09-0.37). Kappa coefficient between PHQ-2 and MINI for depression was .458 and 0.46 for HADS-D.Limitations: Since this study was done with people attending hospital, which could has implications for the prevalence of depression, affecting the validity indicators of the instrument.Conclusions: PHQ-2 show an acceptable test performance in the context of the study. However, the test could yield a considerable amount of false positives that would require specialized evaluation to establish a reliable diagnosis. [ABSTRACT FROM AUTHOR]

Background: This research sought to review studies that examined the factor structure of the PHQ-9 using a confirmatory factor analysis approach (Study 1); to review studies that tested the measurement invariance of the PHQ-9 (Study 2); to examine the psychometric properties of the European Portuguese version in the general population (Study 3).Methods: Using PRISMA guidelines, a search was performed on Web of Science, PsycINFO, and Scopus from 2001 to August 2019. Assessment of eligibility criteria and data extraction were conducted by two independent researchers (Studies 1 and 2). In Study 3, data were collected from 1479 Portuguese adults, using a cross-sectional design. The BDI-II and the GDS-15 were administered to examine convergent validity.Results: The systematic review identified four-factor models of the PHQ-9 (Study 1). Nineteen studies supported a one-factor model, whereas 12 found evidence for a two-factor model. Both models were supported in general, clinical, psychiatric, and international samples. Study 2 identified ten studies that examined PHQ-9 measurement invariance across 18 groups. The PHQ-9 measurement invariance was fully supported across studies. Study 3 revealed that a two-factor model showed a close fit to data in the European Portuguese version of the PHQ-9. Measurement invariance, reliability, and convergent and divergent validity were also established.Limitations: Study 3 did not include a gold standard measure of depression to evaluate PHQ-9 diagnostic properties.Conclusions: Conceptual implications of the findings are discussed, and recommendations for using the Portuguese version of the PHQ-9 as a screening measure in community settings are also highlighted.

Background: Affective dysregulation is central to depression. However, emotion regulation (ER) tendencies in depression remain poorly understood. It is critical, therefore, to validate measures of habitual ER in clinical populations. The current study aimed to validate the Cognitive Emotion Regulation Questionnaire (CERQ) in a sample of individuals with a history of recurrent depression who are currently in remission.Method: The CERQ measures ER tendencies with 36 self-report items that are divided into nine subscales. Each subscale is purported to assess one of five adaptive and four maladaptive ER strategies. The CERQ was administered to 476 adults (mean age = 46.76 years; 75% female) that were currently in remission with a history of recurrent depression, who were recruited from primary care settings. We first investigated the CERQ's nine factor structure, internal consistency, convergent and criterion validity.Results: The nine-factor structure did not fit the CERQ structure in a sample of individuals with recurrent depression and convergent validity was poor. Instead, a five-factor structure fit the data best and showed acceptable convergent and criterion validity.Limitations: The generalisability of the findings may be limited due to relative lack of diversity in terms of gender and ethnicity of the sample.Conclusion: These results suggest that the taxonomic structure of the CERQ does not fit emotion regulation patterns in adults with a history of depression. These findings highlight the importance of validating measures in clinical samples. [ABSTRACT FROM AUTHOR]

Background: The recently released 11th edition of International Classification of Diseases (ICD-11) included new definitions of disorders specifically associated with stress. Complex post-traumatic stress disorder (CPTSD) was included in ICD-11 as a new trauma-related disorder which could develop following prolonged or reoccurring traumatic experiences. Research on ICD-11 PTSD and CPTSD validity and epidemiology has, so far, mostly been conducted in adult population. This is the first study to explore the construct validity of the Child and Adolescent version of International Trauma Questionnaire (ITQ-CA) as a measure of ICD-11 CPTSD symptoms.Methods: The study was based on a sample of 932 adolescents from the general population aged 12-16 (M = 14.25, SD = 1.27) years exposed to various traumatic experiences. We used confirmatory factor analysis (CFA) and latent class analysis (LCA) to test validity of the ITQ-CA scores from adolescents.Results: The best fitting measurement model included six correlated factors representing the three PTSD and three DSO symptom clusters. LCA analysis revealed four classes whose symptom profiles were reflective of 'CPTSD', 'PTSD', 'DSO only', and 'Baseline'.Conclusions: Findings of the study provide support for the construct validity of the ICD-11 PTSD and CPTSD among adolescents.

Background: Emotional dysregulation (ED) is a heterogenous construct with great relevance in psychiatric research and clinical practice. In the present study, we validated a 40-items version of the Reactivity, Intensity, Polarity and Stability questionnaire (RIPoSt-40), a self-report measure of ED.Methods: A non-clinical sample (N = 396) and two clinical samples of patients with cyclothymia (N = 120) and ADHD (N = 54) were recruited. Items were selected and subscales were derived based on inter-item correlations and PCA with promax rotation in the non-clinical sample. Test-retest reliability was assessed in a subsample (N = 60). Internal consistency and concurrent validity with TEMPS-M factors were evaluated in each sample. The three groups results were compared to ascertain discriminant validity.Results: Four subscales were identified as measures of affective instability, emotional impulsivity, negative and positive emotionality. The first three subscales also sum up to a negative ED score comprising thirty items. Measures of reliability (test-retest r = 0.71-0.84) and internal consistency (Cronbach's α = 0.72-0.95) were generally high. Concurrent validity was supported by correlations with TEMPS-M factors. Discriminant validity was significant (p < 0.001) with cyclothymic and ADHD patients showing higher scores for each subscale, except for positive emotionality.Limitations: The non-clinical sample was recruited through a web-survey and mainly included young and highly educated subjects. Mood and anxiety comorbidity of the clinical samples were not taken into consideration.Conclusion: RIPoSt-40 questionnaire has proved to be a valid, reliable and useful tool to assess ED both in clinical and non-clinical contexts.
