Psychometric properties of the Specific Phobia Dimensional Scale in an Australian adult community sample

ABSTRACT Objective The Specific Phobia Dimensional Scale (SP-D) is a 10-item scale developed by the Diagnostic and Statistical Manual (Fifth Edition) Anxiety, Obsessive-Compulsive Spectrum, Posttraumatic and Dissociative Disorder work group to supplement current categorical approaches to Specific Phobia (SP) assessment. The aim of the current study was to examine the psychometric properties of the SP-D in an Australian community sample. Method A total of 285 participants (74% female) aged 18–76 years (M = 28.15; SD = 12.01) completed the study. A smaller subsample (n = 18) completed the measures of interest a second time to examine test–retest reliability. Results Confirmatory factor analysis indicated a unidimensional factor structure of the SP-D (root mean square error of approximation [RMSE] = 0.13; comparative fit index [CFI] = 0.94). Internal consistency and test–retest reliability was high (a = 0.95 and Intraclass Correlation Coefficient [ICC] = 0.95, respectively). The measure demonstrated adequate convergent validity with the Specific Phobia Questionnaire (SPQ; r s = 0.54), and unsatisfactory divergent validity with the Fear Questionnaire – Agoraphobia subscale (FQ-Ag; r s = 0.45). Conclusions Overall, the findings suggest that the SP-D can reliably and briefly measure SP symptoms within an Australian community sample. Further research is required to investigate divergent validity. Replication of the test–retest results are required due to small sample size. Overall, this study is limited in its female-biased convenience sample and recruitment methodologies.

Validity and Reliability Study of the Turkish Version of the "Uncivil Behavior in Clinical Nursing Education Scale" for Nursing Students.

Background and Purpose: Nursing undergraduate students may encounter unkind behaviors during their clinical education. This study aimed to test the psychometric properties of the Turkish version of the "Uncivil Behavior in Clinical Nursing Education (UBCNE) Questionnaire," which measures nursing students' perceived levels of uncivil behavior in the clinical learning environment. Methods: The study was conducted in four steps: translation, face and content validity, confirmatory factor analysis, and reliability assessment. Data were collected from 216 nursing students from Turkey. Results: In the exploratory factor analysis (EFA), a unidimensional factor structure with an eigenvalue above 1 was detected, and therefore the scale was analyzed as a single dimension. In the EFA with 13 items, the Kaiser-Meyer-Olkin value was 0.943, and the Barlett test result was 1862.965 (p <05). The fit indices for the class were calculated as χ2/df = 2.218, root-mean-square error of approximation = .075, and comparative fit index = 0.961. Cronbach's coefficient α (alpha) for Turkish culture was .942. Conclusion: The study showed that the Turkish version of the UBCNE scale is a valid and reliable measurement tool for assessing perceived incivil behaviours in nursing students' clinical education.

First psychometric evaluation of the Level of Personality Functioning Scale-Brief Form 2.0 in adolescents.

Reflecting the recent consensus that challenges in personality functioning often onsets in adolescence, and the move toward dimensional models of personality pathology such as the level of personality functioning (LPF) of the alternative model for personality disorders, it is important to have validated measures that can assess LPF in young people. The Level of Personality Functioning Scale-Brief Form 2.0 (LPFS-BF 2.0) is the briefest measure of LPF and may be particularly well suited for assessing LPF in youth; however, it has yet to be formally validated in youth. Therefore, the current investigation evaluated the psychometric properties of the LPFS-BF 2.0 in adolescents drawn from a community sample of ethnically diverse North American youth (N = 194, age 12-18; 58% female). Factor structure, gender invariance, reliability, convergent validity, incremental validity, and criterion validity were evaluated. Results demonstrated support for the LPFS-BF 2.0's unidimensional factor structure, as well as high internal consistency. Configural, metric, and scalar measurement invariance was supported across male and female genders, as well as convergent validity. Relative to the Personality Inventory for the DSM-5 Brief Form and Levels of Personality Functioning Questionnaire 12-18, the LPFS-BF 2.0 demonstrated additional variance in predicting borderline personality features, and internalizing and externalizing problems. Study findings support the English version of the LPFS-BF 2.0 as a brief and psychometrically sound instrument for assessing LPF in youth and adolescents.

The UFair-Questionnaire: Perceived university fairness and its association with mental health

Abstract Introduction University students face different stressors that might jeopardise their mental health. Hitherto, mainly general stress perceptions were assessed, which appeared inappropriate to indicate stress directly linked to the university or for deriving specific preventative measures. The aim of this study was to adapt the concept of organisational justice to universities, develop and validate a corresponding questionnaire (UFair: University Fairness Questionnaire), and estimate its association with mental health. Methods In total, 1,105 students (average age: 25.5 years [SD: 5.43]; female: 50.1%; university: 67.2%, university of applied sciences: 32.8%) were surveyed online. Perceived unfairness at the university was measured using the newly developed 20 item UFair Questionnaire. Mental health was measured using the Patient Health Questionnaire (PHQ-8, depression) and Maslach Burnout Inventory for Students (MBI-SS, burnout). Linear regression models estimated the adjusted (age, gender, type of university, lifestyle factors) relationship between perceived university injustice and mental health indicators. Results The UFair questionnaire showed good psychometric properties (Cronbach’s alpha = .960) and a unidimensional factor structure. There was a considerable association with depression (beta = .485; p &amp;lt; .001; R2 = .261) and burnout (beta = .481; p &amp;lt; .001; R2 = .250). Conclusions Perceived injustice represents not only a stressor at the workplace but also in the university setting, showing a considerable relationship with students’ mental health. University justice includes the perception of organisational aspects, the treatment of students, and consideration of the individual situation of students. The relevance of these aspects to the health of students should be recognised and taken into account by universities. The valid measurement by the UFair Questionnaire represents the basis for possible preventive approaches and interventions. Key messages • Organisational injustice exists not only in the workplace but also among students in the university setting. • Perceived unfairness among students is associated with depression and burnout.

Validation of the Warwick-Edinburgh Mental Well-Being Scale for the Mental Health Surveillance (MHS) of German adults

BackgroundMental health encompasses more than just the absence of mental disorders. Thus, a Mental Health Surveillance (MHS) and reporting system for Germany should monitor mental well-being in addition to psychopathology to capture a more complete picture of population mental health. The Warwick-Edinburgh Mental Well-Being Scale (WEMWBS) is an internationally established inventory for the integrated assessment of different aspects of mental well-being (i.e., hedonic and eudaimonic) in population samples that has not yet been validated for Germany.MethodsUsing data from a cross-sectional online survey of a convenience sample of N = 1.048 adults aged 18–79 years (51% female) living in Germany, the factorial structure, measurement invariance (age, sex) and psychometric properties of the WEMWBS in its long (14 items) and short (7 items) versions were analyzed. Additionally, correlations to relevant factors (e.g., health-related quality of life, psychological distress) were investigated as indicators of criterion validity.ResultsMeans of model fit indices did not confirm a unidimensional factor structure for either version. The three-factor-correlative models showed moderate to good fit while the bifactor model with one general mental well-being factor and three grouping factors fitted the data best. The full range of possible responses was used for all items, and the distribution of both scales was approximately normal. Moreover, the results revealed measurement invariance across sex and age groups. Initial evidence of criterion validity was obtained. Internal consistencies were α = 0.95 and α = 0.89, respectively. Average mental well-being was comparable to that of other European countries at 3.74 for the long version and 3.84 for the short version. While there were no differences by sex, comparisons between age groups revealed higher mental well-being among the older age groups.ConclusionsBoth versions of the WEMWBS showed sound psychometric characteristics in the present German sample. The findings indicate that the instrument is suitable for measuring mental well-being at the population level due to its distributional properties. These results are promising, suggesting that the scale is suitable for use in a national MHS that aims to capture positive mental health in the population as a foundation for prevention and promotion efforts within public mental health.

Validity and Reliability of the Sickle Cell Self-Efficacy Scale in an Online, Anonymous Sample of Adults Living With Sickle Cell Disease.

Background and Purpose: The aim of the study was to examine the psychometric properties of the Sickle Cell Self-efficacy Scale (SCSES) in an anonymous, online cohort of adults with sickle cell disease (SCD). Methods: The SCSES was completed by 60 adults with SCD. An exploratory factor analysis was conducted. Convergent validity and discriminant validity were assessed using bivariate correlations between the SCSES and other study variables, and internal consistency reliability was evaluated through examining an alpha coefficient. Results: A unidimensional factor structure explained 49.6% of the variance in self-efficacy. The SCSES demonstrated convergent validity and discriminant validity with the select battery of measured concepts and sufficient internal consistency reliability (Cronbach's alpha = .87). Conclusions: The SCSES remains a valid and reliable measure of SCD self-efficacy among adults when used in anonymous, online research.

Evaluating the Psychometric Properties of the Gratitude Questionnaire in a Chinese Sample: Comparing the 6-Item and 5-Item Versions

Abstract Objectives There are controversies related to the item composition of the Gratitude Questionnaire-Six-Item Form (GQ-6). Recent literature has suggested removing Item 6 from the scale. This study evaluated both the 6- and 5-item versions and proposed an adapted Chinese version. Method Nine hundred and three undergraduate students were recruited for this psychometric evaluation study. The internal consistency, concurrent validity, and construct validity of the GQ-6 were evaluated. Results The results showed that the 5-item Gratitude Questionnaire (GQ-5), which excludes Item 6, demonstrated better internal consistency (α = 0.74) compared to the original 6-item version (GQ-6) (α = 0.59). Both the 6-item and 5-item versions of the Gratitude Questionnaire exhibited good concurrent validity with well-established measures of self-esteem, life satisfaction, happiness, and mental well-being, as reported in the gratitude literature. The confirmatory factor analysis (CFA) results indicated that the 5-item version possessed better construct validity than the original version. The CFA results also supported a unidimensional factor structure for the GQ-5 after post-hoc modifications. Conclusions The findings suggest that the GQ-5 demonstrates better psychometric properties compared to the original GQ-6. These results will assist researchers in choosing the appropriate version of the Gratitude Questionnaire for research studies conducted in different Chinese contexts. Preregistration This study is not preregistered.

Florence Bullying-Victimization Scales: Validation Study and Victimization Associations With Well-Being and Social Self-Efficacy

This study provides a thorough psychometric evaluation of construct and criterion validity and measurement invariance of the promising Florence Bullying-Victimization Scales (FBVS). A special focus was devoted to the concurrent criterion validity of the victimization scale with regard to well-being and social self-efficacy. Exploratory and confirmatory multidimensional item response theory and structural equation modeling were applied to cross-sectional data retrieved from 3rd to 6th-grade Czech primary school students ( N = 1795; 49% female; M age = 10.42, SD = 1.25). The results supported the use of unidimensional factor structure that demonstrated acceptable model fit and measurement invariance across genders and grades. Moderate to high correlations of the FBVS scores with bullying and victimization measured by the Olweus Bully/Victim Questionnaire and other instruments indicated very good convergent validity. Regarding criterion validity, higher victimization was associated with lower levels of well-being and social self-efficacy.

Measuring Self-Efficacy for Exercise among Older Adults: Psychometric Properties and Measurement Invariance of a Brief Version of the Self-Efficacy for Exercise (SEE) Scale.

(1) Background: Physical activity is known to promote health and psychological well-being in older adults, yet global inactivity rates in this population remain high. Among the factors associated with physical activity, self-efficacy for exercise represents a key predictor for developing effective interventions in older adults. This study aimed to validate the Self-Efficacy for Exercise Scale (SEE) in individuals over 65. (2) Methods: A sample of 726 older adults from the USA and Italy (51.1% females; age range = 65-95 years; Mage = 72.57, SDage = 6.49) completed the SEE, along with the Godin-Shepard Leisure-Time Physical Activity Questionnaire (GSLTPAQ), the Big Five Inventory 2-Extra Short Form (BFI-2-XS), and the 12-item Short Form Health Survey (SF-12). (3) Results: The SEE showed a Cronbach's Alpha of 0.88 and a Composite Reliability of 0.89. Moreover, it demonstrated a unidimensional factor structure and good fit indices. Full measurement invariance was achieved across gender and age, while partial scalar invariance was found across countries, suggesting minor cultural differences. Correlation with the GSLTPAQ, the BFI-2-XS, and the SF-12 support the convergent and nomological validity of the SEE. (4) Conclusions: These findings provide evidence that the SEE is a reliable and valid measure of self-efficacy for exercise among older adults and that the items are interpreted similarly across different ages, genders, and cultures.

The Everyday Wellbeing Appraisal Scale: Assessing a type of subjective well-being uniquely associated with health behavior in people with hypertension.

Everyday well-being appraisals are judgments about the goodness of recent daily life events. These appraisals are expected to be distinct from other types of well-being involving traits, affect, and psychological distress and expected to be uniquely important for understanding health behavior such as exercise, diet, and treatment adherence for people with medical conditions. To develop and test a new Everyday Wellbeing Appraisal Scale, two studies were conducted in which a total of 718 people with hypertension completed online questionnaires. In Study 1, to achieve maximum validity with the fewest number of items, an empirical analysis was used to select a set of six items with high discrimination that incorporated multiple types of response-option formats. In Study 2, the scale's unidimensional factor structure and high discrimination were confirmed, and the new scale outperformed several existing types of well-being scales in its ability to explain unique variance in health behavior criterion variables. Specifically, it explained unique variance in health behavior after controlling for a widely used measure assessing trait-level reflections of well-being, as well as measures of positive affect and two types of psychological distress. Also, when compared to the trait-level measure of well-being, the new scale demonstrated less overlap with affect and psychological distress. These results suggest that this brief, new scale is valuable for assessing a distinct construct that is especially salient for understanding health behavior.

Shared decision-making in healthcare: development and assessment of the translated Finnish version of the SDM-Q-9.

The aim of this study was to assess the cultural validity and reliability of a Finnish version of the nine-item Shared Decision-Making Questionnaire (SDM-Q-9) in a sample of patients with different sociodemographic characteristics. The original SDM-Q-9 was translated into Finnish with the agreement of the developers of the original scale. The standardised translation procedure was followed by a pilot test of the questionnaire. The data were collected from an online questionnaire. Reliability was estimated by Cronbach's alpha. Structural validity of the questionnaire was assessed by confirmatory factor analysis. The pilot study assessing the cultural validity of the scale was a success, as it did not find any expressions needing to be revised. The Finnish version of the SDM-Q-9 - the SDM-Q-9-FIN - was tested in the study where a total of 736 patients responded to the questionnaire. The questionnaire yielded high reliability with a Cronbach's alpha of 0.92. Confirmatory factor analysis confirmed the unidimensional factor structure with Item 1 excluded. The SDM-Q-9-FIN was shown to be a reliable instrument for evaluating shared decision-making among Finnish patients. Further testing and research are recommended among a greater diversity of patient groups.

VISCERAL SENSITIVITY INDEX (VSI-IT): Italian Adaptation and Validation.

The Visceral Sensitivity Index (VSI) represents a significant advancement in the assessment of gastrointestinal-specific anxiety among patients with irritable bowel syndrome (IBS) and chronic inflammatory bowel diseases (IBD)-such as ulcerative colitis and Crohn's disease. However, an Italian version of the instrument is not yet available for the Italian-speaking population. This study utilized a national sample of 500 individuals divided into four groups: (a) patients with Crohn's disease, (b) patients with ulcerative colitis, (c) patients with IBS, and (d) healthy controls (individuals without any diagnoses) to test the validity and reliability of the Italian VSI. Using back-translation methodology to ensure translation fidelity, this research applied a questionnaire and the VSI through an online format to 500 participants. Confirmatory Factor Analysis (CFA) revealed that the Italian VSI had excellent psychometric properties, demonstrating high internal consistency (Cronbach's α = 0.949) and construct validity. The scale proved sensitive in detecting significant differences in visceral sensitivity among groups, highlighting its utility as a clinical and research assessment tool. Specifically, the Italian VSI exhibited a unidimensional factorial structure and maintained a strong correlation with interoceptive awareness, type of disease, and gastrointestinal symptom severity, confirming its role in enhancing the understanding and management of IBD and IBS in Italy.

Evaluation of the critical warzone experiences scale among Gulf War I-era veterans: Associations with PTSD symptoms, depressive symptoms, and suicidal thoughts and behaviors

ABSTRACT Prior research has established the psychometric properties of the Critical Warzone Experiences (CWE) scale among post-9/11 Iraq/Afghanistan-era veterans; however, the psychometric properties of the CWE among Gulf War I-era veterans have not yet been established. The first objective of the present study was to examine the psychometric properties of the CWE among Gulf War I-era veterans. The second objective was to test the hypothesis that the CWE would have a significant indirect effect on suicidal thoughts and behaviors via posttraumatic stress disorder (PTSD) and depressive symptoms. To test these hypotheses, a survey packet that included the CWE and measures of PTSD symptoms, depressive symptoms, and suicidal thoughts and behaviors was administered to 1,153 Gulf War I-era veterans. Consistent with prior research in post-9/11 Iraq/Afghanistan-era veterans, the CWE exhibited good internal consistency (α = .85), a unidimensional factor structure (RMSEA = .056, CFI = .959, SRMR = .033; average factor loading = .69), and good concurrent validity with PTSD (r = .47, p < .001) and depressive (r = .31, p < .001) symptoms among Gulf War I-era veterans. Additionally, as hypothesized, a significant indirect effect from the CWE to suicidal thoughts and behaviors via PTSD and depressive symptoms (β = .35, p < .001) was also observed. Taken together, our findings provide strong support for using the CWE with Gulf War I-era veterans.

Assessing gastrointestinal symptoms in people with autism: Applying a new measure based on the Rome IV criteria

BackgroundPeople with autism spectrum disorder (ASD) often struggle with gastrointestinal symptoms, implicating alterations of the gut-microbiota-brain axis, which has also been linked to sensory reactivity, pain, and gastro-intestinal symptoms in ASD. To better understand the prevalence and impact of gastrointestinal symptoms among individuals with ASD, a measure is needed that adhere to the Rome IV criteria of gastrointestinal symptoms and is applicable to individuals with ASD. The Gastrointestinal Symptom Severity Scale (GSSS) is a new assessment tool designed to match this need. MethodsIn a diverse sample of 265 individuals with ASD (mean age = 9.44, SD = 4.99), we examined the psychometric properties of the GSSS, the prevalence of gastrointestinal symptoms and associations with ASD traits, sensory sensitivity, repetitive behaviors, and pain. ResultsA unidimensional factor structure of the GSSS was confirmed and the measure showed good internal consistency, adequate test-retest reliability and strong convergent validity. Around a third of the participants evidenced clear difficulties with gastrointestinal symptoms and gastrointestinal symptoms were strongly associated with more pronounced ASD traits, sensory reactivity, and repetitive behaviors. ConclusionsThe GSSS shows promise as a useful measure to analyze the prevalence, severity, and impact of gastro-intestinal symptoms in individuals with ASD.

First Psychometric Evaluation of the English Version of the Semi-Structured Interview for Personality Functioning (STiP-5.1)

The Alternative Model for Personality Disorders provides a dimensional framework for the conceptualization of personality disorders where Criterion A concerns the assessment of one’s level of personality functioning (LPF). This study examines the psychometric properties of the English translation of the Semi-Structured Interview for Personality Functioning (STiP-5.1) to validate this translation for the assessment of LPF in English-speaking populations; and examine whether this measure increments self-report measures of LPF and personality pathology in predicting general functioning. The sample consisted of 129 emerging adults between 18 and 25 years of age (M = 20.54, SD = 2.08) from a mixed college and clinical sample. Results support a unidimensional factor structure of the STiP-5.1, good internal consistency, and high inter-rater reliability. Construct validity was supported through associations of the STiP-5.1 with self-report measures of LPF and personality pathology. The STiP-5.1 incremented self-report measures of personality pathology in predicting functional impairment, though additional variance explained was modest. Finally, STiP-5.1 scores differentiated individuals who obtained a score at or above the clinical cutoff from those below on self-report measures of personality pathology and LPF with large effect sizes. Findings support the validity of the English translation of the STiP-5.1 for the assessment of LPF.

Characterizing personal recovery in severe mental illness: French psychometric validation of the Questionnaire about the Process of Recovery (QPR-Fr).

The support of the personal recovery of people with lived experience of mental illness is a major issue in clinical practice. Thus, a valid instrument to assess personal recovery is needed. The present study aimed to validate the French translation of the 22-item Questionnaire about the Process of Recovery (QPR-Fr). A convenience sample of 222 participants reporting a severe mental illness diagnosis was recruited online. Psychometric properties of the QPR-Fr were evaluated. A confirmatory factor analysis was conducted for structural validity. Internal consistency and test-retest reliability were assessed. To test for convergent validity, we conducted multiple linear regression analysis to explore the QPR-Fr associations with psychological distress and the CHIME framework (with Connectedness, Hope and optimism about the future, Identity, Meaning in life, and Empowerment) proxy measures (perceived social support, hope, self-esteem, quality of life, and empowerment). An adequate fit was found for a 19-item unidimensional factor structure. Internal consistency was excellent. Test reliability was good. The QPR-Fr total score was significantly positively associated with quality of life, hope, self-esteem, and social support satisfaction and negatively associated with psychological distress. No significant association was found with social support availability nor with empowerment. This study provides additional data to support the cross-cultural validity of the Questionnaire about the Process of Recovery. The QPR-Fr is a valid and reliable tool to assess personal recovery. Practitioners could use the QPR-Fr to assess personal recovery in collaboration with people with lived experience. Convergent validity with CHIME proxy measures supports the validity of the CHIME framework in a French cultural context. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Assessment of Children’s Skill in Noticing Unfamiliar Words within Informational Context

ABSTRACT Reading and language standards, such as the Common State Standards for English Language Arts, indicate that primary-grade students should be able to determine the meaning of unfamiliar words from grade-level context. However, to be able to attempt determining the meaning of an unfamiliar word, the word must first be noticed. There is a lack of research on young children developing skill in noticing unfamiliar words, which may be an important skill for their vocabulary development and comprehension. In the present study, theories of word learning, earlier experimenter-created assessments with older learners, and research with multilingual learners guided the development of such an assessment, the Noticing Unfamiliar Words Assessment (NUWA). Instrument development methods, including expert review and piloting, were performed prior to administering the NUWA to a sample of 55 second graders. Results of the exploratory factor analysis supported the hypothesized unidimensional factor structure and indicated that the assessment had an adequate fit and internal consistency reliability. Findings suggest that the NUWA may be helpful in better understanding the developmental nature of skill in noticing unfamiliar words from context while listening and how it contributes to children’s vocabulary knowledge and other literacy skills.

Adaptation and Psychometric Properties of an Attitude toward Artificial Intelligence Scale (AIAS-4) among Peruvian Nurses.

The integration of Artificial Intelligence (AI) into various aspects of daily life has sparked growing interest in understanding public attitudes toward this technology. Despite advancements in tools to assess these perceptions, there remains a need for culturally adapted instruments, particularly in specific contexts like that of Peruvian nurses. To evaluate the psychometric properties of the AIAS-4 in a sample of Peruvian nurses. An instrumental design was employed, recruiting 200 Peruvian nurses. The Attitude toward Artificial Intelligence in Spanish (AIAS-S), a cultural and linguistic adaptation of the AIAS-4, involved data analysis using descriptive statistics, confirmatory factor analysis (CFA), and invariance tests. The Confirmatory Factor Analysis (CFA) confirmed a unidimensional factor structure with an excellent model fit (χ2 = 0.410, df = 1, p = 0.522, CFI = 1.00, TLI = 1.00, RMSEA = 0.00, SRMR = 0.00). The scale demonstrated high internal consistency (α = 0.94, ω = 0.91). Tests of invariance from configural to strict confirmed that the scale is stable across different demographic subgroups. The AIAS-S proved to be a psychometrically solid tool for assessing attitudes toward AI in the context of Peruvian nurses, providing evidence of validity, reliability, and gender invariance. This study highlights the importance of having culturally adapted instruments to explore attitudes toward emerging technologies in specific groups.

Turkish Adaptation and Psychometric Evaluation of the Relationship Mindfulness Measure in an Emerging Adult Sample

While latest research has accepted the importance of mindfulness in mental health, its role in interpersonal well-being receives less attention, including the necessary measurement tools. This study aimed to translate the Relationship Mindfulness Measure (RMM) into Turkish and explore its psychometric properties with unmarried Turkish emerging adults. A total of 191 university students (age range 18–29, M = 22.90, SD = 2.78) in committed romantic relationships participated in this study. The convergent validity analysis revealed a positive relation of RMM with trait mindfulness ( r = .47, p &lt; .001) and a negative relation with negative affect ( r = −.21, p = .05). Internal and test-retest reliability of RMM was acceptable ( α = .78, r = .67). The unidimensional factor structure of 5-item RMM was supported, and no common method variance was observed. Overall, findings indicated that Turkish RMM is a valid and reliable measure to assess emerging adults’ relationship mindfulness.

Evaluating the Validity and Measurement Invariance of the Patient Health Questionnaire-9 Among Canadian Nurses.

Background and Purpose: The patient health questionnaire 9 item (PHQ-9) is a widely used self-reported measure for screening depressive symptoms. This study aims to examine measurement invariance and psychometric properties of the PHQ-9 for screening depressive symptoms in nurses across different nursing roles, gender, and workplace sector. Methods: The study is a secondary analysis of pre-COVID and COVID-19 survey data from 4,176 nurses and 3,238 nurses in British Columbia. Data from the PHQ-9 tested the assumption of unidimensionality, reliability, and presence of differential item functioning (DIF). Results: The PHQ-9 showed excellent internal consistency (r = .9) and a unidimensional factor structure. PHQ-9 items were free of DIF across nursing roles, gender, and workplace sector. Conclusions: This study supported the valid use of the PHQ-9 as a screening tool for depressive symptoms among nurses.
