A Comprehensive Psychometric Evaluation of the Future Self-Continuity Questionnaire
Future self-continuity is the relationship between an individual's perception of their present and future selves and is attracting intense interest from researchers in psychology and health. This study aimed to psychometrically evaluate the Future Self-Continuity Questionnaire (FSCQ), a tool designed to measure an individual's future self-continuity, in New Zealand's unique sociocultural context. In Phase 1 we tested the reliability (internal con…
Decolonising outcome measurement
The objective of the study is to conduct a systematic review and methodological quality appraisal on studies reporting the development of health and wellbeing outcome measures for Māori (Indigenous people of New Zealand), identify common features and processes, and critically appraise the measures using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN). Key databases were searched using key terms in May 20…
It’s harder than just saying hi
Forming and sustaining social connections is integral to university students’ sense of belonging and well-being, yet many face challenges in building meaningful relationships. This study explored these challenges through 20 semi-structured interviews with recent first year students. Using thematic analysis, five key themes emerged: (1) Barriers in forming social connections, (2) Strategies used to connect with other students, (3) Sustaining socia…
An exploratory study of the mental health and emotional challenges of women inside Ghanaian witches’ camps
For years, older women accused of witchcraft have been persecuted and forced into sanctuaries known as witch camps. This highlights a lack of public policies and social support for older women facing disabilities, aging, and dementia. Labelling them as witches and isolating them from their families and familiar surroundings profoundly impacts their emotional well-being. However, little is known about the mental health of older women in witch camp…

Enhancing the precision of the Positive and Negative Affect Schedule (Panas) using Rasch analysis
Stigmatising and Racialising Covid-19
The Asian community - the second largest non-European ethnic community in New Zealand - plays an important role in combatting the COVID-19 pandemic, evidenced by their active advocation for border control and mass masking. Despite the long history of racial discrimination against the Asian population, the Asian community has experienced certain degrees of racial discrimination associated with the stigmatisation as the cause of the COVID-19 outbre…
Strengthening Community End-of-Life Care through Implementing Measurement-Based Palliative Care
The increasing demand for palliative care in New Zealand presents a potential threat to the quality of service delivery. One strategy to overcome this is through the implementation of valid and reliable patient-reported outcome measures. This mixed-methods study aimed to (1) implement measurement-based palliative care (MBPC) in a community palliative care service in Auckland, New Zealand; (2) evaluate the clinical utility of MBPC perceived by cli…
Rasch analysis and ordinal-to-interval conversion tables for the Depression, Anxiety and Stress Scale
This study conducted Rasch analysis of the Depression, Anxiety and Stress Scale using responses of 400 participants to produce ordinal-to-interval conversion algorithms not available to date. Minor modifications such as removing the non-fitting item 5 and combining subscales items into super-items were necessary to achieve the best model fit ( χ2(15) = 20.28, p = 0.16). The results support internal validity of the modified 20-item Depression, Anx…
Rasch analysis of the Perceived Stress Scale
Rasch analysis was conducted to enhance the precision of the widely used 10-item Perceived Stress Scale using two datasets ( n = 450 each) randomly selected from samples of the New Zealand general population ( n = 1102), New Zealand university students ( n = 479) and US university students ( n = 396). The best Rasch model fit ( χ2(27) = 29.92, p = .36), good person separation reliability (.80) and coverage (98%) of the sample by the scale items w…
Longitudinal validity and reliability of the Myeloma Patient Outcome Scale (MyPOS) was established using traditional, generalizability and Rasch psychometric methods
The MyPOS demonstrated good longitudinal measurement properties, with potential areas for revision being the Healthcare Support subscale and the rating scale. The new psychometric approaches should be used for testing validity of monitoring in clinical settings
A novel symptom cluster analysis among ambulatory HIV/Aids patients in Uganda
Symptom clusters are gaining importance given HIV/AIDS patients experience multiple, concurrent symptoms. This study aimed to: determine clusters of patients with similar symptom combinations; describe symptom combinations distinguishing the clusters; and evaluate the clusters regarding patient socio-demographic, disease and treatment characteristics, quality of life (QOL) and functional performance. This was a cross-sectional study of 302 adult …
Evaluating quality of life outcomes following joint replacement
Toward a comprehensive theory of child sexual abuse
In recent years a number of multifactorial theories of child sexual abuse have been developed. The most influential are Finkelhor's (1984) Precondition Model of child sexual abuse; Hall and Hirschman's (1992) Quadripartite Model; and Marshall and Barbaree's Integrated Theory (1990). While all three of these important theories have a number of strengths, each has serious weaknesses that limit its ability to provide a satisfactory explanation of ch…
Evolutionary psychology
Evolutionary psychology has recently experienced a rapid and often controversial growth in popularity and influence that has been evident in both the academic and the popular press. The aim of this article is to explain what evolutionary psychology is, to give a brief account of its history and evolution, and to give a balanced account of some of the major issues or criticisms. This paper traces the early influences of Darwinian thought on psycho…
Dimensions of Distress
A brief 20-item measure of psychological distress, the GHQ20, was administered to three diverse ethnic groups, which included Chinese, Filipino, and Maori subjects. The FACTOREP method was employed to see if the previously reported four-factor structure of the GHQ20 could then be replicated. The four-factor structure was clearly replicated across the three groups. It is suggested that this measure may be useful for future cross-cultural studies i…
Factor Analysis of the Wais-R Using the Factor Replication Procedure, Factorep
The factor structure of the WAIS-R has been the subject of much debate and recently researchers have examined multiple independent samples and compared the resulting factor structures using the coefficient of congruence. On the basis of this, one recent study concluded that the WAIS-R had three clear factors. In the present study this conclusion was questioned and it was claimed that the previous result was an artifact caused by the large general…

Multiple replication of the factor structure of the inventory of socially supportive behaviors
Interest in the beneficial effects of social support for the physical and psychological well-being of individuals has rapidly grown. The Inventory of Socially Supportive Behaviors is one promising new questionnaire that has been designed to measure this psychosocial dimension. While in many ways this is a psychometrically sound questionnaire, the number of stable factors it includes has yet to be established. This problem was solved in the presen…
