This article aimed to develop the Multidimensional Vaccine Hesitancy Scale (MVHS). In Study 1 ( n = 336), we identified 13 possible vaccine hesitancy dimensions and developed an item list. In Study 2 ( n = 444), we performed an exploratory factor analysis that supported an eight-dimension structure and reduced our measure to 32 items. We supported its validity by establishing relations with associated variables, even while controlling for measures of the same and similar constructs. In Study 3 ( n = 575), we confirmed its factor structure and replicated its validity results. Support was provided for the psychometric properties and validity of the MVHS.

The Impact

Background and Purpose: The purpose of this study was to determine a factor structure for the Impact of Miscarriage Scale (IMS). The 24 items comprising the IMS were originally derived from a phenomenological study of miscarriage in women. Initial psychometric properties were established based on a sample of 188 women (Swanson, 1999a). Method: Data from 341 couples were subjected to confirmatory factor analysis (CFA) and exploratory factor analysis (EFA). Results: CFA did not confirm the original structure. EFA explained 57% of the variance through an 18-item, 4-factor structure: isolation and guilt, loss of baby, devastating event, and adjustment. Except for the Adjustment subscale, Cronbach’s alpha coefficients were ≥.78. Conclusion: Although a 3-factor solution is most defensible, with further refinement and additional items, the 4th factor (adjustment) may warrant retention.

AbstractThere is growing interest in quantifying attitudes towards autistic people, however there is relatively little research on psychometric properties of the only existing measure and its ability to predict engagement with people with autism. To begin addressing these issues, we compared three scales measuring attitudes towards autistic people following the development of two new measures. Exploratory factor analysis, across two datasets, revealed that the factor-structure of an established 16-item scale is unclear. Further, its predictive validity of intended engagement with autistic people was comparable to our novel and psychometrically robust 1- and 4-item measures of attitudes towards autistic people. We therefore conclude that a 1- or 4-item scale is sufficient to measure general attitudes towards autistic people in future research. Equally, we propose that additional research is required to develop measures that are grounded in theoretical models of attitude formation and therefore distinguish between different components of attitudes.

Using a Hong Kong–sourced sample of participants, this study set out to validate the Chinese version of the Attitudes Toward Prisoners (ATP-C) Scale and evaluate its psychometric properties. To provide further evidence for the ATP-C Scale’s validity, it was then administered to three groups varying in their volunteering experience in Hong Kong. Exploratory factor analysis revealed a four-factor structure that differs from the unidimensional model proposed by the scale developers. Cronbach’s alpha values were satisfactory for all four subscales, and construct validity of the ATP-C Scale was also assessed with a second sample of participants. Implications for the assessment of attitudes toward prisoners away from a one-dimensional spectrum and further directions for cross-cultural studies on related topics are discussed.

Background: It has been shown that food craving contribute to the development of weight and food-related pathologies. Thus, an accurate measurement of food craving is important for clinical and research purposes. Aim: We aimed to evaluate the psychometric properties of the reduced version of the Food Craving Questionnaire-Trait (FCQ-T-r), an internationally validated tool, in Farsi. Methods: For this cross-sectional study, 153 students of the University of Tehran were recruited between February and March 2019. Study measures included demographic characteristics, the Farsi version of FCQ-T-r, food craving questionnaires, Depression, Anxiety and Stress Scale (DASS-21), and the Quality of Life questionnaire (WHOQOL-BREF). Confirmatory factor analysis using SPSS AMOS (version 21) failed to support the one-factor structure of FCQ-T-r in Farsi, so we conducted an exploratory factor analysis to investigate the factor structure of the questionnaire. Results: Exploratory factor analysis found a 3-factor structure: factor 1 “preoccupation with food”, factor 2 “lack of control over eating” and factor 3 “emotional eating” explaining 73.3% of the variance. Internal consistency of the FCQ-T-r was excellent (McDonald’s ω = 0.950). The FCQ-T-r scores were correlated with body mass index, DASS-21, and WHOQOL-BREF values, which supports concurrent validity of the tool. Conclusion: The Farsi version of FCQ-T-r is a reliable and valid self-administrated tool to measure food craving traits among Iranian university students. Given the unstable factor structure of the questionnaire in different studies, further research to explore the factor structure of the tool is warranted.

The objective of this study was to develop a questionnaire to assess the online sexual solicitation and interactions of minors with adults in order to document the extent of this problem. The questionnaire was constructed in four phases: (a) a review of the previous literature; (b) interviews with convicted online child-sex offenders; (c) a review of the questionnaire items by experts; and (d) a pilot study of the questionnaire administered to adolescents. The validation sample consisted of 2,731 minors (12-15 years old, 50.6% girls). Exploratory factor analysis revealed a two-factor structure. The first factor, called “sexual solicitation,” included items referring to sexual requests from an adult to a minor. The second factor, termed “sexualized interactions,” included items indicating an adult groomed a minor with the purpose of committing a sexual offense. Of participants, 12.6% reported sexual solicitations, and 7.9% reported sexualized interactions. These findings open possible directions for research on the characteristics and consequences of online sexual solicitation and abusive interactions.

Background: After introducing the emotional schema model, two questionnaires are proposed to assess this structure. This study is the first validation research on the Relationship Emotional Schema scale (RESS) worldwide. Objectives: The present study aimed to assess the factor structure and psychometric properties of RESS among Iranian victims of domestic violence. Materials and Methods: This study used a correlational method, and the research population encompassed couples with the experience of domestic violence, who had referred to the Forensics Center of Sari Province in 2018. The sample size of the study was determined to be 227 persons selected by the convenience sampling method. To implement RESS for Iranian population after back translation, a pilot study was conducted on 50 persons. Moreover, internal consistency and exploratory factor analysis were performed to check its structure validity. Results: Fourteen items have a significant correlation with the scores of the relevant subscale (negative and positive relationship emotional schema). The reliability of these two dimensions was acceptable, as confirmed by Cronbach’s alpha coefficient with a range of 0.68 to 0.74. The total value of Cronbach’s alpha coefficient was 0.71. Exploratory factor analysis revealed four factors of RESS. Furthermore, a two-factor structure was extracted, and the correlation between items confirmed the structure validity of the scale. Convergent validity analyses revealed that negative and positive relationship emotional schemas had a significant correlation with the domestic violence domains and its total score and with neuroticism and extraversion. Conclusions: According to the present findings, RESS can be utilized in research and clinical practice.

Objective. The Dental Activities Test (DAT) was developed to be used by dental, nursing, and other health professionals to assess the ability of persons with dementia to perform oral health-related activities and aid care planning. The instrument was designed as a unitary scale and has excellent internal consistency, test-retest reliability, interrater reliability, and construct validity. This study examines the underlying factor structure of the DAT among older adults in assisted living settings. Methods. In a secondary analysis of the data from the original study, the results of testing of 90 older adults with normal to severely impaired cognition from three assisted living communities in North Carolina from March 2013 to February 2014 were studied. An exploratory factor analysis was used to assess the dimensionality of the presumed unitary assessment scale. Results. Two-factor structures were explored. A one-factor model demonstrated acceptably mixed model fit, and a two-factor model had good model fit with moderate correlation between the two factors (r=0.667, p<0.05). All the items in the one-factor model demonstrated significant factor loadings (loadings ≥ 0.39, all p<0.05), while the loadings of some items in the two-factor model (nonsignificant or cross-loadings, loadings < 0.40) did not meet the criteria of factor selection. The one-factor structure was preferred based on the criteria of Scree Plot, eigenvalue, and factor interpretability in relation to clinical relevance. Conclusions. The study provided preliminary evidence that the Dental Activities Test has a unidimensional construct among older adults with cognitive impairment. It suggested that this instrument can be used as a unitary scale to assess dental-related function in persons with dementia. Future testing, including using a confirmatory factor analysis, in a new sample is needed to further assess the usefulness and psychometric properties of this instrument.

The current study examined the factor structure and the psychometric properties of Sandra Prince-Embury’s Resiliency Scale for Adolescents (RESA) in Chinese undergraduates. A total of 726 undergraduate students were randomly divided into two subsamples: Sample A was used for the exploratory factor analysis (EFA) and Sample B was used for the confirmatory factor analysis (CFA). The EFA revealed that 56 items and a model of 10 factors with 3 higher order factors (as described by Sandra) were to be retained; CFA with Sample B confirmed this result. The overall scale and the subscales of the Chinese-RESA demonstrated a high level of internal consistency. Furthermore, concurrent validity was demonstrated by the correlation of the scale with other instruments such as the PANAS and the CSS, and the predictive validity was confirmed via three multiple regression analyses using the PANAS as a criterion variable: one for the 10 subscales of the C-RESA, one for the 3 higher order scales, and one for the total C-RESA. We concluded that the C-RESA may be used for research into Chinese undergraduates’ adaptive behaviors.

Abstract Background: Effective monitoring of cognitive behaviour therapy (CBT) competence depends on psychometrically robust assessment methods. While the UK Cognitive Therapy Scale – Revised (CTS-R; Blackburn et al., 2001) has become a widely used competence measure in CBT training, practice and research, its underlying factor structure has never been investigated. Aims: This study aimed to present the first investigation into the factor structure of the CTS-R based on a large sample of postgraduate CBT trainee recordings. Method: Trainees (n = 382) provided 746 mid-treatment audio recordings for depression (n = 373) and anxiety (n = 373) cases scored on the CTS-R by expert markers. Tapes were split into two equal samples counterbalanced by diagnosis and with one tape per trainee. Exploratory factor analysis was conducted. The suggested factor structure and a widely used theoretical two-factor model were tested with confirmatory factor analysis. Measurement invariance was assessed by diagnostic group (depression versus anxiety). Results: Exploratory factor analysis suggested a single-factor solution (98.68% explained variance), which was supported by confirmatory factor analysis. All 12 CTS-R items were found to contribute to this single factor. The univariate model demonstrated full metric invariance and partial scalar invariance by diagnosis, with one item (item 10 – Conceptual Integration) demonstrating scalar non-invariance. Conclusions: Findings indicate that the CTS-R is a robust homogenous measure and do not support division into the widely used theoretical generic versus CBT-specific competency subscales. Investigation into the CTS-R factor structure in other populations is warranted.

The purpose of this study was to describe the development of the Gastrointestinal and Gastroesophageal Reflux (GIGER) Scale for Infants and Toddlers, and determine its factor structure and psychometric properties. Items were developed to comprehensively assess gastrointestinal (GI) and gastroesophageal reflux (GER) symptoms observable by a parent. Exploratory factor analysis on 391 responses from parents of children under 2 years old resulted in a 36-item scale with 3 subscales. Internal consistency reliability was acceptable (α = .78-.94). The GIGER total score and all 3 subscales were correlated with the Infant Gastroesophageal Reflux Questionnaire-Revised (I-GERQ-R) ( P < .05) and Infant Gastrointestinal Symptoms Questionnaire (IGSQ) ( P < .05). GIGER total score was higher in infants with a diagnosis of GER ( P < .05) or constipation ( P < .05) compared to those without. The GIGER is a parent-report measure of GI and GER symptoms in children under 2 years old with adequate psychometric properties.
