Cross-cultural adaptation,reliability, and validity of the Persian version of the Cumberland Ankle Instability Tool

Purpose: The purpose of the present study was to translate and to cross-culturally adapt the Cumberland Ankle Instability Tool (CAIT) into Persian language and to evaluate its psychometric properties.

Method: The International Quality of Life Assessment process was pursued to translate CAIT into Persian. Two groups of Persian-speaking individuals, 105 participants with a history of ankle sprain and 30 participants with no history of ankle sprain, were asked to fill out Persian version of CAIT (CAIT-P), Foot and Ankle Ability Measure (FAAM), and Visual Analog Scale (VAS). Data obtained from the first administration of CAIT were used to evaluate floor and ceiling effects, internal consistency, dimensionality, and criterion validity. To determine the test–retest reliability, 45 individuals re-filled CAIT 5–7 days after the first session.

Results: Cronbach’s alpha was over the cutoff point of 0.70 for both ankles and in both groups. The intra-class correlation coefficient was high for right (0.95) and left (0.91) ankles. There was a strong correlation between each item and the total score of the CAIT-P. Although the CAIT-P had strong correlation with VAS, its correlation with both subscales of FAAM was moderate.

Conclusions: The CAIT-P has good validity and reliability and it can be used by clinicians and researchers for identification and investigation of functional ankle instability.

• Implications for Rehabilitation

• Chronic ankle instability is one of the most common consequences of acute ankle sprain.

• Cumberland Ankle Instability Tool is an acceptable measure to determine functional ankle instability and its severity.

• The Persian version of Cumberland Ankle Instability Tool is a valid and reliable tool for clinical and research purpose in Persian-speaking individuals.

     

Further Validation of the Dutch Version of the Enright Forgiveness Inventory

This study examined the reliability, construct validity, and factor pattern of the Dutch version of the Enright Forgiveness Inventory (EFI) in a sample of 731 respondents (heterosexually married adults, 359 males and 372 females) in Belgium. The Cronbach α for EFI total (.98) and all its subscales, Positive Affect (PA) (.95), Negative Affect (NA) (.92), Positive Behaviour (PB) (.94), Negative Behaviour (NB) (.94), Positive Cognition (PC) (.95), Negative Cognition (NC) (.93) were high. The construct validity of the scale was measured by a 1-item scale. The 1-item scale proved to be positive, strong and significantly (p < .001) correlated with EFI (.73). Principal components analysis in an Initial Factor Method found a one-factor solution confirming the unidimensional structure of EFI.

Reliability and validity of the Japanese version of the Dysexecutive Questionnaire (DEX) in Alzheimer's disease: validation of a behavioral rating scale to assess dysexecutive symptoms in Japanese patients with Alzheimer's disease

BACKGROUND: Both executive cognitive dysfunction and behavioral problems contribute to dysexecutive symptoms in daily life. The aim of the present study was to develop a behavior rating scale for assessing dysexecutive symptoms in Japanese patients with AD. METHOD: The Dysexecutive Questionnaire (DEX), devised by Burgess et al. (1998), was used to evaluate 122 Japanese patients with AD. The factor structure, internal consistency, test-retest reliability, and construct validity of the Japanese version of the DEX were then examined. RESULTS: The Japanese version of the DEX demonstrated a good internal reliability and a good test-retest reliability. Factor analysis revealed three factors that were named 'apathy', 'hyperactivity' and 'planning and monitoring process of the purposive action'. The 'apathy' factor of the DEX was significantly correlated with the 'apathy' score of the Neuropsychiatric Inventory (NPI), while 'planning and monitoring process' factor of the DEX was significantly correlated with the total score of the Frontal Assessment Battery (FAB) and the 'hyperactivity' factor of the DEX was significantly correlated with the 'aggression', 'euphoria' and 'disinhibition' scores of the NPI. CONCLUSIONS: The Japanese DEX is a reliable and valid instrument for assessing executive dysfunction conveniently in real life situations of AD patients. While two factors, 'apathy' and 'hyperactivity', were associated with emotional and behavioral changes, the 'planning and monitoring process' was associated with the cognitive executive function in the patients with AD. These findings suggest that both a neuropsychiatric syndrome and cognitive function contribute to the dysexecutive symptoms experienced by AD patients in daily life.     

Portuguese version of Corah's Dental Anxiety Scale: transcultural adaptation and reliability analysis

This study explores the psychometric properties of the Portuguese version of Corah's Dental Anxiety Scale (DAS), an instrument designed to assess the manifestations of dental anxiety. The DAS has been translated into several languages, but no adaptation and reliability analysis of the Portuguese version of the scale has yet been carried out. A total of 747 Brazilian undergraduate students participated in this study. The instrument proved to have good internal consistency and test-retest reliability. Furthermore, we observed that women are more anxious during dental treatment routines compared to men. Our findings suggest that the Portuguese version of DAS is a reliable instrument for assessing adults' dental anxiety traits, and can be used for both clinical and research purposes.
