Mental fog is a core symptom of fibromyalgia. Its definition and measurement are central to an understanding of fibromyalgia-related cognitive disability. The Mental Clutter Scale was designed to measure mental fogginess. In an exploratory factor analysis of two different samples ( n = 128 and n = 170), cognitive symptoms of fibromyalgia loaded on 2 dimensions: cognition and mental clarity. The mental clarity factor comprised 8 items with factor loadings greater than .60 and was named the Mental Clutter Scale. The factor stability of the new scale was good, internal consistency was .95, and test-retest reliability over a median of 5 days was .92. The 8-item scale is a quick measure of mental fog that provides clinicians with information about cognitive functioning in fibromyalgia.

Advance Care

Background: Although patients prefer that physicians initiate advance care planning (ACP) conversations, few physicians regularly do so. Physicians may be reluctant to initiate ACP conversations because they lack self-efficacy in their skills. Yet, no validated scale on self-efficacy for ACP exists. Our objective was to develop a scale that measures physicians’ ACP self-efficacy (ACP-SE) and to investigate the validity of the tool. Methods: Electronic questionnaires were administered to a random sample of family medicine physicians (n = 188). Exploratory factor analysis was performed to determine whether the scale was multidimensional. An initial assessment of the scale’s validity was also conducted. Results: The exploratory factor analysis indicated that a single factor was appropriate using all 17 items. A single, unidimensional scale was created by averaging the 17 items, yielding good internal consistency (Cronbach α = 0.95). The average scale score was 3.94 (standard deviation = 0.71) on a scale from 1 to 5. The scale was moderately correlated with a global single-item measure of self-efficacy for ACP ( r = .79, P < .001), and the scale differentiated between physician groups based on how much ACP they were doing, how recently they had an ACP conversation, formal training on ACP, and knowledge of ACP. In a multivariate analysis, the ACP-SE scale was a strong predictor of the percentage of patients with chronic life-limiting diseases with whom the physician discussed ACP. Conclusion: The final ACP-SE scale included 17 items and demonstrated high internal consistency.

The capacity to direct attention (CDA) is a pivotal facet of cognitive functioning that allows people to focus on trains of thought, complex tasks, and the daily business of life. According to a theoretical framework of directed attentional fatigue (DAF) and restoration, excessive demand for attention depletes CDA, a condition called DAF. Attentional demands are factors such as feelings of loss and worries that require intense or prolonged use of CDA and thus can lead to DAF. The purposes of this study were to determine reliability and validity for an instrument to measure attentional demands, the Attentional Demands Survey (ADS). The ADS was administered to 197 (142 females, 50 males) community-dwelling elderly (ages 65-98 years, M = 77). A factor analysis revealed 4 factors/subscales consistent with theorized domains. Internal consistency for each subscale ranged from .87 to .90 and test-retest reliability was .91. The ADS can be used to explore the relationships among attentional demands, CDA, and interventions to support and restore attentional functioning for elders.

This article presents findings from the statistical test of an instrument designed to measure youth’s perceptions of the life skills that were improved as a result of their participation in 4-H Clubs. The questionnaire was administered to 126 4-H club members in Florida. The 19-item self-rating Life Skills Improvement Scale was examined for face and content validity. The results were also submitted for exploratory factor analysis and internal consistency testing. The factor analysis yielded a four-factor solution to the 19-item scale, which accounted for 62.6% of the variance in the scale. The Cronbach’s alpha reliability coefficient for the 19 items was 0.88. The article also discusses implications and future use of the instrument, as well as recommendations for further study.

The objective of this research was to use the technique of Exploratory Factor Analysis (EFA) for the adequacy of a tool for the assessment of fish consumption and the characteristics involved in this process. Data were collected during a campaign to encourage fish consumption in Brazil with the voluntarily participation of members of a university community. An assessment instrument consisting of multiple-choice questions and a five-point Likert scale was designed and used to measure the importance of certain attributes that influence the choice and consumption of fish. This study sample was composed of of 224 individuals, the majority were women (65.6%). With regard to the frequency of fish consumption, 37.67% of the volunteers interviewed said they consume the product two or three times a month, and 29.6% once a week. The Exploratory Factor Analysis (EFA) was used to group the variables; the extraction was made using the principal components and the rotation using the Quartimax method. The results show clusters in two main constructs, quality and consumption with Cronbach Alpha coefficients of 0.75 and 0.69, respectively, indicating good internal consistency.

Background:Clinicians commonly fail to use cognitive behavioural therapy (CBT) adequately, but the reasons for such omissions are not well understood.Aims:The objective of this study was to create and validate a measure to assess clinicians’ attitudes towards CBT – the Negative Attitudes towards CBT Scale (NACS).Method:The participants were 204 clinicians from various mental healthcare fields. Each completed the NACS, measures of anxiety and self-esteem, and a measure of therapists’ use of CBT and non-CBT techniques and their confidence in using those techniques. Exploratory factor analysis was used to determine the factor structure of the NACS, and scale internal consistency was tested.Results:A single, 16-item scale emerged from the factor analysis of the NACS, and that scale had good internal consistency. Clinicians’ negative attitudes and their anxiety had different patterns of association with the use of CBT and other therapeutic techniques.Conclusions:The findings suggest that clinicians’ attitudes and emotions each need to be considered when understanding why many clinicians fail to deliver the optimum version of evidence-based CBT. They also suggest that training effective CBT clinicians might depend on understanding and targeting such internal states.

Children's Grief

The Concerns of Grieving Caregivers Scale (COGCS) is the first of its kind to explore caregivers’ concerns about their own parenting, as well as their relationships with, and specific behaviours of their bereaved child(ren). Using exploratory factor analysis, we evaluate grieving parents’ and caregivers’ concerns using data collected across clinical populations from two community organizations supporting grieving families (i.e., a children’s grief centre and a community hospice). Two identified factors were established: Concerns about Caregiving and Concerns about the Child. The COGCS demonstrates good internal consistency and criterion validity in its application with two distinct clinical samples. The use of this scale could be of value to clinicians supporting bereaved caregivers and their families as they can integrate concern-specific resources into their practice to better support their clients’ presenting concerns.

AbstractObjectiveThe present study aimed to develop and validate a questionnaire assessing perceived food environment in a French-Canadian population.DesignA questionnaire, the Perceived Food Environment Questionnaire, was developed assessing perceived accessibility to healthy (nine items) and unhealthy foods (three items). A pre-test sample was recruited for a pilot testing of the questionnaire. For the validation study, another sample was recruited and completed the questionnaire twice. Exploratory factor analysis was performed on the items to assess the number of factors (subscales). Cronbach’s α was used to measure internal consistency reliability. Test–retest reliability was assessed with Pearson correlations.SettingOnline survey.SubjectsMen and women from the Québec City area (n 31 in the pre-test sample; n 150 in the validation study sample).ResultsThe pilot testing did not lead to any change in the questionnaire. The exploratory factor analysis revealed a two-subscale structure. The first subscale is composed of six items assessing accessibility to healthy foods and the second includes three items related to accessibility to unhealthy foods. Three items were removed from the questionnaire due to low loading on the two subscales. The subscales demonstrated adequate internal consistency (Cronbach’s α=0·77 for healthy foods and 0·62 for unhealthy foods) and test–retest reliability (r=0·59 and 0·60, respectively; both P<0·0001).ConclusionsThe Perceived Food Environment Questionnaire was developed for a French-Canadian population and demonstrated good psychometric properties. Further validation is recommended if the questionnaire is to be used in other populations.

Abstract Background Outcome measurement is an essential part of the evaluation of palliative care and the measurements need to be reliable, valid and adapted to the culture in which they are used. The Integrated Palliative Outcome Scale (IPOS) is a widely used tool for assessing outcomes in palliative care. The aim of this study was to provide Czech version of IPOS and asses its psychometric properties.Methods Patients receiving palliative care in hospice or hospitals completed IPOS and part of the sample also completed Edmonton Symptom Assessment System (ESAS) and Palliative Performance Scale (PPS). The reliability of Czech IPOS was tested with Cronbach alpha (internal consistency) and Intraclass correlation coefficient and Weighted Kappa (test-retest reliability). Construct validity was assessed with factor analysis (Exploratory Factor Analysis) and convergent validity was tested with correlation analysis (Spearman correlation).Results Sample consisted of 140 patients (mean age 72; 90 women; 81% oncologic disease). IPOS internal consistency was 0.789; ICC= 0.88. To study convergent validity, we assessed the correlations of IPOS with ESAS (R= 0.4) and PPS (R= -0.2), however, these results have to be considered preliminary due to the small sample size. Exploratory factor analysis revealed a 2-factor solution on our data. The first factor covers emotional and information needs and the second factor covers physical symptoms.Conclusion Czech IPOS has very good reliability regarding both internal consistency and test-retest reliability. Together with an item analysis results, we can conclude that the Czech adaptation of the tool was successful. The convergent validity needs to be assessed on the larger sample and the proposed 2-factor internal structure of the questionnaire has to be confirmed by using CFA.

OBJECTIVE: To translate, culturally adapt, and validate the psychometric characteristics of the Italian version of the Dance Functional Outcome Survey (DFOS-IT) in adult dancers. DESIGN: Clinical measurement study. METHODS: The DFOS-IT was forward translated, reconciled, backward translated, and reviewed by an expert committee to establish optimal correspondence with the original English DFOS. We examined test-retest reliability in 58 dancers within a 10-day period, using intraclass correlation coefficients (ICC2,1). In a sample of 265 healthy and injured dancers, the following were examined: 1) construct validity, comparing the DFOS-IT to SF-36 using Pearson correlations; 2) exploratory factor analysis and internal consistency; and 3) sensitivity, by generating receiver operating characteristic curves and determining area under the curve (AUC). In a subgroup of 44 dancers, we determined internal responsiveness across three time-points using repeated measures ANOVA (p<0.05). Injured dancers’ scores were analyzed for floor and ceiling effects. RESULTS: The DFOS-IT demonstrated very high test-retest reliability (ICC=0.98). Single-factor loading in exploratory factor analysis supported unidimensionality of the scale, with high internal consistency (a=0.93). DFOS-IT total, activities of daily living (ADL), and Dance Technique scores had strong construct validity compared with scores on the SF-36 PCS (r=0.71). There was excellent sensitivity, with high AUC values (AUC=0.80). There were significant differences across time for DFOS-IT scores (p<0.001), demonstrating responsiveness to change, and no floor or ceiling effects. CONCLUSION: The DFOS-IT is a valid, reliable, and responsive tool that can be used as an outcome and screening measure for Italian adult ballet and modern dancers following lower extremity or low back injury.

Abstract Background: Outcome measurement is an essential part of the evaluation of palliative care and the measurements need to be reliable, valid and adapted to the culture in which they are used. The Integrated Palliative Outcome Scale (IPOS) is a widely used tool for assessing personal-level outcomes in palliative care. The aim of this study was to provide Czech version of IPOS and asses its psychometric properties. Methods: Patients receiving palliative care in hospice or hospitals completed the IPOS. The reliability of Czech IPOS was tested with Cronbach alpha (for internal consistency), the intraclass correlation coefficient for total IPOS score and weighted Kappa (for test-retest reliability of individual items). Factor analysis was used for elucidating the construct (Exploratory Factor Analysis). Convergent validity was tested with correlation analysis (Spearman correlation) in a part of the sample, who completed also the Edmonton Symptom Assessment System (ESAS) and the Palliative Performance Scale (PPS). Results: The sample consisted of 140 patients (mean age 72; 90 women; 81 % oncological disease). The Cronbach alpha was 0.789; intraclass correlation was 0.88. The correlations of IPOS with ESAS was R= 0.4 and PPS R= -0.2. Exploratory factor analysis revealed a 2-factor solution on our data. The first factor covers emotional and information needs and the second factor covers physical symptoms. Conclusion: Czech IPOS has very good reliability regarding both internal consistency and test-retest reliability. Together with an item analysis results, we can conclude that the Czech adaptation of the tool was successful. The convergent validity needs to be assessed on the larger sample and the proposed 2-factor internal structure of the questionnaire has to be confirmed by using CFA.
