Interbattery Factor Analysis

Questionnaires used in health promotion programs are too rarely subjected to tests of reliability and validity prior to their use. Without such tests, any information gathered must be suspect. The complexity of such tests is illustrated by the investigation of the validity of a revised version of the Multidimensional Health Locus of Control (MHLC) Scales. Confirmatory maximum-likelihood factor analysis was used to analyze data from 519 elementary school students. The concurrent validity of the revised MHLC was also evaluated by conducting an interbattery factor analysis that included data from selected “marker” items from the measure developed by Parcel and his colleagues. The results supported the validity of the revised MLHC Scales when used with children.

The objective of this study was to examine the factor structure, reliability, and validity of the Form C of the Multidimensional Health Locus of Control scales in adolescents. A confirmatory factor analysis indicated that adequate fit of a four-factor model and the internal consistency of the scales were adequate. Criterion validity of the four scales of the Form C of the Multidimensional Health Locus of Control was also supported by significant correlations with measures of pain-related self-efficacy, anxiety, and coping strategies. The results indicate that the four Form C of the Multidimensional Health Locus of Control scale scores are reliable and valid and therefore support their use to assess pain-related locus of control beliefs in adolescents.

Background: Negative symptoms are core features of schizophrenia and very challenging to be treated. Identification of their structure is crucial to provide a better treatment. Increasing evidence supports the superiority of a five-factor model (alogia, blunted affect, anhedonia, avolition, and asociality as defined by the NMIH-MATRICS Consensus); however, previous data primarily used the Brief Negative Symptoms Scale (BNSS). This study, including a calibration and a cross-validation sample (n = 268 and 257, respectively) of participants with schizophrenia, used the Clinical Assessment Interview for Negative Symptoms (CAINS) to explore the latent structure of negative symptoms and to test theoretical and data-driven (from this study) models of negative symptoms.Methods: Exploratory factor analysis (EFA) was carried out to investigate the structure of negative symptoms based on the CAINS. Confirmatory factor analysis (CFA) tested in a cross-validation sample four competing theoretical (one-factor, two-factor, five-factor, and hierarchical factor) models and two EFA-derived models.Result: None of the theoretical models was confirmed with the CFA. A CAINS-rated model from EFA consisting of five factors (expression, motivation for recreational activities, social activities, vocational, and close/intimate relationships) was an excellent fit to the data (comparative fix index = 0.97, Tucker–Lewis index = 0.96, and root mean square error of approximation = 0.07).Conclusions: This study cannot support recent data on the superiority of the five-factor model defined by the NMIH-MATRICS consensus and suggests that an alternative model might be a better fit. More research to confirm the structure of negative symptoms in schizophrenia, and careful methodological consideration, should be warranted before a definitive model can put forward and shape diagnosis and treatment of schizophrenia.

The aim of this study was to determine the psychometric properties of the Spanish version of the SOC-13 in Colombian adults. The SOC-13 questionnaire was administered to 489 individuals aged ≥18 years who were in lockdown from March to July 2020 in Nariño County, Colombia. Psychometric properties of the scale were examined using a cross-validation method via exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Additionally, configural and metric invariance were tested. To determine the internal consistency of the questionnaire, McDonald’s omega (ω), Cronbach’s alpha (α), and composite reliability (CR) coefficients were estimated. The EFA determined that a three-factor structure best fit the data (comprehensibility, manageability, and meaningfulness) and CFA confirmed this three-factor model structure showing a good fit (χ2S-B = 188.530, χ2S-B/(62) = 3.615, p = 0.001; NNFI = 0.959; CFI = 0.968; RMSEA = 0.052 (90% CI [0.041–0.063]) and SRMR = 0.052).The invariance analysis indicated the same underlying theoretical structure between genders. Additionally, (ω), (α), and (CR) coefficients confirmed a high internal consistency of the instrument. The SOC-13 scale, reflecting comprehensibility, manageability, and meaningfulness, is a reliable and valid tool for assessing the sense of coherence in Colombian populations.

The purpose of the study was to develop a diabetes locus of control scale and to assess its validity and reliability. Factor analysis of the items was conducted utilizing varimax orthogonal rotation. Three factors were identified representing Internal (6 items), Chance (6 items) and Powerful Others (6 items) orientations. The subscales were internally consistent, Cronbach alphas were .75, .77 and .72 for the Internal, Chance, and Powerful Others scales. Test-retest reliabilities were for the subscales, Internal .77, Chance .72, and Powerful Others .66. Criterion-related validity with the Multidimensional Health Locus of Control scale was established. Reading level was at tenth grade. It is recommended that the more specific Diabetes Locus of Control scale be utilized in studies assessing locus of control for diabetics.

Adequate Reliability

The Achievement Motives Scale (AMS) is a well-established and frequently used scale to assess hope of success and fear of failure. In three studies with German-speaking samples (N = 3523, N = 132, N = 126), the authors developed a revised form of the AMS using confirmatory factor analysis. As found in previous research, the original 30-item set of the AMS did not provide an acceptable fit to a two-factor model. In contrast, a revised 10-item version (AMS-R) provided an adequate fit to the theoretically intended two-factor model. The adequate fit could be validated in cross-validation procedures. Furthermore, the revised scales provided adequate reliability, lower interscale correlations, and criterion-related validity with respect to typical criteria of achievement-related behavior.

Abstract. The Therapist Adherence Measure (TAM-R) is a central assessment within the quality-assurance system of Multisystemic Therapy (MST). Studies into the validity and reliability of the TAM in the US have found varying numbers of latent factors. The current study aimed to reexamine its factor structure using two independent samples of families participating in MST in the Netherlands. The factor structure was explored using an Exploratory Factor Analysis (EFA) in Sample 1 ( N = 580). This resulted in a two-factor solution. The factors were labeled “therapist adherence” and “client–therapist alliance.” Four cross-loading items were dropped. Reliability of the resulting factors was good. This two-factor model showed good model fit in a subsequent Confirmatory Factor Analysis (CFA) in Sample 2 ( N = 723). The current finding of an alliance component corroborates previous studies and fits with the focus of the MST treatment model on creating engagement.
