    Evaluation of the factor structure of the Adult Manifest Anxiety Scale – Elderly version (AMAS-E) in community dwelling older adult New Zealanders
    (New Zealand Psychological Society, 2016) Roberts MH; Fletcher RB; Merrick PL
    Background: The measurement of anxiety in older adults is problematic due to insufficient evidence of content and discriminant validity for existing anxiety measures used with older adult populations. The Adult Manifest Anxiety Scale - Elderly Version (AMAS-E) is a measure of anxiety developed specifically for older adults. However, there has been limited psychometric data published to enable clinicians to evaluate its appropriateness for older adult populations. This study provides information on the validity and clinical utility of the AMAS-E within a New Zealand population. Method: 203 community dwelling older adult New Zealanders responded. Three competing models were trialled using confirmatory factor analysis. Convergent and discriminant validity were evaluated between the AMAS-E and the Hospital Anxiety and Depression Scale (HADS). Results: Variable internal consistency was observed for the subscales of the AMAS-E. Reasonable fit was observed for both the higher-order and correlated AMAS-E models. However the Lie subscale showed no significant relationship with the other factors, and consequently was removed. Model fit worsened, however the model was retained as it was more theoretically plausible and justifiable statistically. Correlations between the AMAS-E and the HADS revealed moderate convergent but poor discriminant validity. Conclusion: The factor structure of the AMAS-E was not strongly supported. The observed limited validity of this anxiety measure for older adults in its present form, suggests the need for a revision and its clinical use is cautioned.

    Organizational citizenship behavior in civil society workplaces
    (John Wiley and Sons Inc., 2024-02-01) Langdon S; Fletcher RB; Carr SC
    Organizational citizenship behavior is argued to be particularly important to civil society organizations (Akhtar, Hakeem, & Naeem, 2017). However, organizational citizenship behavior needs further theoretically driven research in the civil society sector, which is the overarching aim of this study which compared two competing models of organizational citizenship behavior within the New Zealand's civil society sector: Organ (1988) and Williams and Anderson (1991) models. Participants were N = 442 employees from 217 civil society organizations in New Zealand. Confirmatory factor analysis tested these two competing measurement models of organizational citizenship behavior. Results suggested employees of civil society organizations tended to perform citizenship behavior in accordance with Organ (1988) structured five-factor model, independent of their organization. Results are discussed, with a focus on why employees working in New Zealand's civil society sector seem to be more likely to perform Organ (1988) model of organizational citizenship behavior, and practical implications presented.
