The Oxford Happiness Questionnaire: Transformation from an Ordinal to an Interval Measure Using Rasch Analysis

The scientific study of happiness requires accurate measurement of the construct that satisfies assumptions of parametric statistics and thus allows both researchers and clinicians to make reliable and valid comparisons with the relevant data sources. The 29-item Oxford Happiness Questionnaire (OHQ) is a widely-used scale for assessment of personal happiness. While its psychometric properties are acknowledged to be acceptable, it presents scores on an ordinal scale and may thus not discriminate precisely between individual happiness levels. The current study aimed to improve precision and item functioning of the OHQ by applying Rasch analysis to a sample of 281 participants. To correct disordered thresholds items were rescored in a uniform fashion. Four items displayed poor relationships with the latent trait of happiness and were removed. Best fit to the unidimensional Rasch model was achieved after locally dependent items were combined into subtests and adjusted for personal differences. Using the ordinal-to-interval conversion tables published here, ordinal OHQ scores can now be transformed to interval level data and thus subjected to parametric statistical analysis without violating fundamental assumptions. The precision of the instrument can be improved significantly by these minor modifications without the need to modify the original response format.     

Classroom engagement dynamics: examining the potency of reflective teaching approach among some selected universities in Ghana

The purpose of this research was to investigate the effectiveness of the use of reflective teaching approach by university lecturers in Ghana to achieve improved student learning outcomes. The research utilised a quantitative survey design involving 180 lecturers who were accidentally or haphazardly selected from four universities in Ghana to complete a reflective teaching survey (RTS) questionnaire. The results showed that participants frequently engaged in varied reflective teaching activities, and were successful in evaluating the effectiveness of their pedagogies. The research concluded that the approach should be an essential component of the teacher performance appraisal system.     

Immigration and Psychosis: an Exploratory Study

This qualitative study aimed to explore views (and related experiences) of healthcare providers regarding immigration and its relation to psychosis, such as schizophrenia, particularly to identify support needs and challenges of immigrants with psychosis and related challenges and enablers of their mental health service providers. The objectives of this study were to identify (1) barriers and enablers of mental health and other services for Canadian immigrants with psychosis and (2) barriers and enablers for their mental health service providers. The study used a phenomenological approach to elicit views of 12 mental healthcare providers with experience in providing mental healthcare to immigrants with psychosis. Semi-structured individual interview data obtained were coded and thematically analyzed. Six themes in relation to the experience of service provision to immigrants with psychosis were found: the immigration process, service availability and accessibility, social determinants of health, cultural context, psychosocial stressors, and enablers and facilitators of recovery. The most prominent challenges/barriers were related to cultural context, language, social and health services, and support. Most mental healthcare providers believed that immigration process precipitates the first episode of psychosis in a majority of immigrants and that psychosis was undetected/non-present when in the country of origin. This study demonstrated system challenges and related opportunities for service provision for immigrants with psychosis. We identified important areas for intervention to reduce disparities for immigrants with psychosis in their use of social and health services. Future directions for research in relation to immigration of people with psychosis are discussed.     

Multicultural Media Use and Immigrant Settlement: A Comparative Study of Four Communities in Ottawa,Canada

Multicultural media serve as important sources of information for immigrant settlement. However, little is known about the role of multicultural media in the process of immigrant settlement. Our aim was to address this gap and to advance understanding of multicultural media use and immigrant settlement through a detailed empirical study involving four ethnocultural and immigrant communities (EICs)—the Chinese, Spanish-speaking Latin American, Somali, and South Asian—in Ottawa, Canada. Using a conceptual framework combining notions of immigrant contexts of reception, and immigrant settlement and information seeking, we present and analyze the findings of a large survey data set (N?=?1212) comparing types of multicultural print, broadcast, and digital media use by immigration category, length of stay, and yearly household income. Based on our findings, we argue that variations exist in the use of multicultural media both within and across the four participating EICs; while factors such as availability of multicultural media as well as length of stay in Canada and, to some extent, household income play a role, immigration category is less significant. Furthermore, we advance that although EICs do use various types of multicultural media, they tend to favor digital media. These findings contribute to improved understanding of the role of multicultural media use in the everyday lives of EICs and provide directions for future research and for the development of relevant policies and practices to address immigrant information needs and facilitate their settlement process.     

The development and validation of the Arabic Scale Of Mental Health (ASMH)

The objective of this research was to develop and validate the Arabic Scale of Mental Health (ASMH) as a generic screening measure and research tool for adults and adolescents. Several samples of both sexes were recruited (N = 3,619). Their ages ranged between 15 and 71 years. The scale has two equivalent versions: Aravic and English. TheASMH comprises 40 brief statements plus 10 filler items. Principal components analysis yielded six components labeled: satisfaction, self-confidence, optimism, enjoyment, meaningful life, and stability. Item-remainder correlations ranged between .31 and .79. Reliabilities in these samples indicated good internal consistency (alphas= .94 to .96) and temporal stability (7- to 10-day test-retest r = .84 to .94). The ASMH significantly and positively correlated with measures of happiness, satisfaction with life, hope, optimism, love of life, and self-actualization, from which one salient component was identified. Therefore, initial convergent and factorial validities were adequate. Male undergraduates obtained a higher mean score than did both their female counterparts and male employed workers, but the effect size was small. It was concluded that the ASMH has good psychometric characteristics in its Arabic version. The English version merits investigation in a cross-cultural study.     

Love of life in Kuwaiti and American college students

In samples of 198 Kuwaiti and 158 American college students, the Love of Life Scale appeared to have good reliability. The American students obtained slightly higher scores than the Kuwaiti students.     

Body image dissatisfaction among adolescent schoolgirls in Jordan

The present study has investigated the occurrence of body image dissatisfaction among adolescent schoolgirls in Amman, Jordan, and the risk factors that are known to predispose it including individual, familial and social variables. A sample of 326 adolescent girls aged 10–16 years was recruited from public and private schools in Amman. Participants completed a socio-demographic data sheet, eating attitude test, and body shape questionnaire. Approximately, 21.2% of participants displayed body image dissatisfaction in which physical changes associated with puberty and exhibiting negative eating attitudes were associated with this dissatisfaction. Additionally, mass media messages, as well as peers and family pressures towards thinness were associated with participants’ preoccupation with their body image. In conclusion, negative body image perception was observed in the present sample. Therefore, well-controlled prospective studies and development of intervention programs on body image among adolescent girls in Jordan are needed.

Recognising faces seen alone or with others: when two heads are worse than one

There is a large body of work investigating face identification, but most of this addresses recognition of a single person. Here, we examine how recognition is affected by the presence of a second face. In Experiments 1 and 2, we demonstrate that memory for an unfamiliar face is severely reduced if it is seen alongside a second person. Sequential presentation of two target faces further reduces accuracy. In Experiments 3 and 4, we demonstrate the same disadvantage for two‐face targets in a matching task, where subjects have no time limits or memory requirement. In matching, the damaging effect of a second face is greatest when the targets are placed close together. Furthermore, there is a general advantage for faces presented to the left. We suggest that it may not be possible to extrapolate results from single‐face studies to experiments (or realistic situations) involving more than one person.

OLD TEXTS,NEW MASKS: A CRITICAL REVIEW OF MISREADING EVOLUTION ONTO HISTORICAL ISLAMIC TEXTS

With the increasing interest in Islam and evolution, some Islamic thinkers have vehemently rejected evolution, while others have eagerly embraced it. However, those seeking to embrace evolution sometimes err in their interpretation of historical writings. Indeed, there are texts written by famous historical scholars of Islam who seem to suggest that humans have evolved from lower forms of species. These include Ibn Khaldūn, Jalāl ad‐Dīn Rūmī, al‐Jāhiz, and The Brethren of Purity (Ikhwān al Safā). Although this may be true, such readings are a mistaken interpretation of the aforementioned authors who are actually referring to some form of the scalae naturae (the Great Chain of Being). This reference to the Great Chain of Being is unknown to some contemporary readers who mistakenly believe these writers to be discussing an evolutionary or a proto‐evolutionary theory. This article demonstrates how and why these historical records do not actually represent any notion of evolution as it is currently understood, in the hope of avoiding any further erroneous claims that seem to be proliferating among modern thinkers.
