  1. Factor Indeterminacy as Metrological Uncertainty: Implications for Advancing Psychological Measurement
    Rigdon EE, Becker JM, Sarstedt M
    Multivariate Behav Res, 2019 03 04;54(3):429-443.
    PMID: 30829544 DOI: 10.1080/00273171.2018.1535420
    Researchers have long been aware of the mathematics of factor indeterminacy. Yet, while occasionally discussed, the phenomenon is mostly ignored. In metrology, the measurement discipline of the physical sciences, uncertainty - distinct from both random error (but encompassing it) and systematic error - is a crucial characteristic of any measurement. This research argues that factor indeterminacy is uncertainty. Factor indeterminacy fundamentally threatens the validity of psychometric measurement, because it blurs the linkage between a common factor and the conceptual variable that the factor represents. Acknowledging and quantifying factor indeterminacy is important for progress in reducing this component of uncertainty in measurement, and thus improving psychological measurement over time. Based on our elaborations, we offer a range of recommendations toward achieving this goal.

  2. Toward understanding Malaysian fishermen's decision making on the use of fishing technology: a mental model approach
    Hamzah A, Krauss SE, Shaffril HA, Suandi T, Ismail IA, Abu Samah B
    Int J Psychol, 2014 Oct;49(5):397-403.
    PMID: 25178962 DOI: 10.1002/ijop.12010
    The vast majority of Malaysia's fishermen are located in rural areas, specifically in the Western and Eastern coastal regions of Peninsular Malaysia and the Sabah and Sarawak central zones. In these areas, the fishing industry is relied upon as a major economic contributor to the region's residents. Despite the widespread application of various modern technologies into the fishing industry (i.e., GPS, sonar, echo sounder, remote sensing), and the Malaysian government's efforts to encourage their adoption, many small-scale fishermen in the country's rural areas continue to rely on traditional fishing methods. This refusal to embrace new technologies has resulted in significant losses in fish yields and needed income, and has raised many questions regarding the inputs to decision making of the fishermen. Drawing on multiple literatures, in this article we argue for the use of a mental model approach to gain an in-depth understanding of rural Malaysian fishermen's choices of technology adoption according to four main constructs--prior experience, knowledge, expertise and beliefs or values. To provide needed inputs to agricultural specialists and related policy makers for the development of relevant plans of action, this article aims to provide a way forward for others to understand dispositional barriers to technology adoption among fishermen who use traditional methods in non-Western contexts.

  4. Fulltext The ability of analysts' recommendations to predict optimistic and pessimistic forecasts

    Previous researches show that buy (growth) companies conduct income increasing earnings management in order to meet forecasts and generate positive forecast Errors (FEs). This behavior however, is not inherent in sell (non-growth) companies. Using the aforementioned background, this research hypothesizes that since sell companies are pressured to avoid income increasing earnings management, they are capable, and in fact more inclined, to pursue income decreasing Forecast Management (FM) with the purpose of generating positive FEs. Using a sample of 6553 firm-years of companies that are listed in the NYSE between the years 2005-2010, the study determines that sell companies conduct income decreasing FM to generate positive FEs. However, the frequency of positive FEs of sell companies does not exceed that of buy companies. Using the efficiency perspective, the study suggests that even though buy and sell companies have immense motivation in avoiding negative FEs, they exploit different but efficient strategies, respectively, in order to meet forecasts. Furthermore, the findings illuminated the complexities behind informative and opportunistic forecasts that falls under the efficiency versus opportunistic theories in literature.

  5. To which world regions does the valence-dominance model of social perception apply?
    Jones BC, DeBruine LM, Flake JK, Liuzza MT, Antfolk J, Arinze NC, et al.
    Nat Hum Behav, 2021 01;5(1):159-169.

    Over the past 10 years, Oosterhof and Todorov's valence-dominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgements of faces. Because this model has primarily been developed and tested in Western regions, it is unclear whether these findings apply to other regions. We addressed this question by replicating Oosterhof and Todorov's methodology across 11 world regions, 41 countries and 11,570 participants. When we used Oosterhof and Todorov's original analysis strategy, the valence-dominance model generalized across regions. When we used an alternative methodology to allow for correlated dimensions, we observed much less generalization. Collectively, these results suggest that, while the valence-dominance model generalizes very well across regions when dimensions are forced to be orthogonal, regional differences are revealed when we use different extraction methods and correlate and rotate the dimension reduction solution.

  6. Coevolutionary Governance of Antibiotic and Pesticide Resistance
    Søgaard Jørgensen P, Folke C, Henriksson PJG, Malmros K, Troell M, Zorzet A, et al.
    Trends Ecol Evol, 2020 Jun;35(6):484-494.
    PMID: 32396815 DOI: 10.1016/j.tree.2020.01.011
    Development of new biocides has dominated human responses to evolution of antibiotic and pesticide resistance. Increasing and uniform biocide use, the spread of resistance genes, and the lack of new classes of compounds indicate the importance of navigating toward more sustainable coevolutionary dynamics between human culture and species that evolve resistance. To inform this challenge, we introduce the concept of coevolutionary governance and propose three priorities for its implementation: (i) new norms and mental models for lowering use, (ii) diversifying practices to reduce directional selection, and (iii) investment in collective action institutions to govern connectivity. We highlight the availability of solutions that facilitate broader sustainable development, which for antibiotic resistance include improved sanitation and hygiene, strong health systems, and decreased meat consumption.

  7. Fulltext Integrating health belief model and technology acceptance model: an investigation of health-related internet use
    Ahadzadeh AS, Pahlevan Sharif S, Ong FS, Khong KW
    J Med Internet Res, 2015;17(2):e45.
    PMID: 25700481 DOI: 10.2196/jmir.3564
    Today, people use the Internet to satisfy health-related information and communication needs. In Malaysia, Internet use for health management has become increasingly significant due to the increase in the incidence of chronic diseases, in particular among urban women and their desire to stay healthy. Past studies adopted the Technology Acceptance Model (TAM) and Health Belief Model (HBM) independently to explain Internet use for health-related purposes. Although both the TAM and HBM have their own merits, independently they lack the ability to explain the cognition and the related mechanism in which individuals use the Internet for health purposes.

  9. Malaysian women's state of well-being: empirical validation of a conceptual model
    Noor NM
    J Soc Psychol, 2006 Feb;146(1):95-115.
    PMID: 16480124
    The author carried out the present study to examine the determinants of Malaysian women's well-being. Specifically, the author proposed a theoretical model of women's roles and well-being--made up of roles, negative affectivity, conflict, and health--and statistically validated it in a group of women occupying both work and family roles (N = 389). Using a life-course approach (P. Moen, 1998) to roles and well-being, the author further examined the model in women of 3 different age groups (age of Group 1 = 20-29 years, age of Group 2 = 30-39 years, and age of Group 3 = 40 years and older). The results supported the proposed model, which showed reasonable fit when applied to the 3 groups of women. The results also indicated that the predictors of women's well-being differ according to their respective age groups. The author discussed these findings in relation to the life-course approach to women's roles.

  10. Depression Following Major Life Transitions in Women: A Review and Theory
    Moustafa AA, Crouse JJ, Herzallah MM, Salama M, Mohamed W, Misiak B, et al.
    Psychol Rep, 2020 Oct;123(5):1501-1517.
    PMID: 31470771 DOI: 10.1177/0033294119872209
    Depression can occur due to common major life transitions, such as giving birth, menopause, retirement, empty-nest transition, and midlife crisis. Although some of these transitions are perceived as positive (e.g., giving birth), they may still lead to depression. We conducted a systematic literature review of the factors underlying the occurrence of depression following major life transition in some individuals. This review shows that major common life transitions can cause depression if they are sudden, major, and lead to loss (or change) of life roles (e.g., no longer doing motherly or fatherly chores after children leave family home). Accordingly, we provide a theoretical framework that explains depression caused by transitions in women. One of the most potential therapeutic methods of ameliorating depression associated with life transitions is either helping individuals accept their new roles (e.g., accepting new role as a mother to ameliorate postpartum depression symptoms) or providing them with novel life roles (e.g., volunteering after retirement or children leave family home) may help them overcome their illness.

  11. Cancer Screening Perception Scale: development and construct validation
    Mahmood MI, Shah SA, Ahmad N, Rosli NM
    J Cancer Educ, 2018 04;33(2):269-277.
    PMID: 27448613 DOI: 10.1007/s13187-016-1081-7
    The aim of this study was to demonstrate the construct validity of a newly developed cancer screening perception scale as a measure of the perception of cancer screening in general among high-risk but healthy asymptomatic groups.The cancer screening perception scale (CSPS) was developed based on extensive literature reviews guided by The Health Belief Model. Fifty-five written items were initially pooled, reviewed by experts for face validity, pretested by 25 healthcare workers and translated into Malay using simple back translation. The scale was then distributed to 300 respondents from two health clinics for construct validation purposes. The obtained data were analyzed using the varimax rotation method for exploratory factor analysis (EFA). The data was submitted for further confirmatory factor analysis using AMOS software.Based on EFA, the results produced five constructs as predicted: perceived severity, perceived susceptibility, perceived benefits, perceived barriers, and cues for action. Two items with low factor loading and unrelated to the recovered domains were removed. Perceived barriers and cues for action had three and two sub-domains respectively which were further confirmed to fit the measurement and structural models. CFA demonstrated the scale fitted GFI = 0.936, CFI = 0.935, RMSEA = 0.076, NORMEDCHISQ = 2.162. The scale discriminated between the domains. Cronbach's alpha for perceived severity, perceived susceptibility, perceived benefits, perceived barrier, and cues for action were 0.907, 0.877, 0.940, 0.864 and 0.938, respectively.The cancer screening perception scale with its promising psychometric properties is now available to measure risks to high-risk but healthy, asymptomatic groups aged 18 and above and can also be used for larger scale study purposes.

  12. Trust in Supervisor and Job Engagement: Mediating Effects of Psychological Safety and Felt Obligation
    Basit AA
    J Psychol, 2017 Nov 17;151(8):701-721.
    PMID: 29043913 DOI: 10.1080/00223980.2017.1372350
    In the social context of job engagement, the role of trust in supervisor in predicting engagement of employees has received attention in research. Very limited research, however, has investigated the mechanisms mediating this dynamic relationship. To address this important gap in knowledge, the aim of this study was to examine psychological safety and felt obligation as two psychological mechanisms mediating the effect of trust in supervisor on job engagement. Drawing from job engagement and social exchange theories, the mediating roles of psychological safety and felt obligation in the trust-engagement relationship were empirically investigated in the Malaysian context. Using self-report questionnaires, data were collected from 337 nurses employed in a public hospital located near Kuala Lumpur, Malaysia. Results fully supported the proposed serial multiple mediator model. Trust in supervisor was indirectly related to job engagement via psychological safety followed by felt obligation. This study provides empirical evidence that trust in supervisor makes employees feel psychologically safe to employ and express their selves in their job roles. This satisfaction of the psychological safety need is interpreted by employees as an important socioemotional benefit that, in turn, makes them feel obligated to pay back to their organization through their enhanced level of job engagement. Implications for theory and practice were discussed.

  13. Working memory and literacy as predictors of performance on algebraic word problems
    Lee K, Ng SF, Ng EL, Lim ZY
    J Exp Child Psychol, 2004 Oct;89(2):140-58.
    PMID: 15388303 DOI: 10.1016/j.jecp.2004.07.001
    Previous studies on individual differences in mathematical abilities have shown that working memory contributes to early arithmetic performance. In this study, we extended the investigation to algebraic word problem solving. A total of 151 10-year-olds were administered algebraic word problems and measures of working memory, intelligence quotient (IQ), and reading ability. Regression results were consistent with findings from the arithmetic literature showing that a literacy composite measure provided greater contribution than did executive function capacity. However, a series of path analyses showed that the overall contribution of executive function was comparable to that of literacy; the effect of executive function was mediated by that of literacy. Both the phonological loop and the visual spatial sketchpad failed to contribute directly; they contributed only indirectly by way of literacy and performance IQ, respectively.

    PMID: 31690004 DOI: 10.3390/ijerph16214283
    Brain Breaks Physical Activity Solutions (BBPAS) is a web-based structured physical activity (PA) video that is specifically designed for school settings and can stimulate a student's health and learning. The purpose of this study is to measure the effect of BBPAS on the stages of change, decisional balance, processes of change, self-efficacy and leisure-time exercise among Malay ethnic primary school children. A validated Malay version of three of the five constructs was derived with sound validity and was used in the present study. A total of 159 male and 163 female children aged 10 to 11 years old, mean (SD) = 10.53 (0.50), were recruited from two schools in Kelantan, Malaysia. Purposive sampling was used to divide the children into intervention (n = 177) and control (n = 145) groups. Children in the intervention group underwent BBPAS activity for an accumulated 30 min per week, while children in the control group were not involved in the BBPAS intervention. Mixed factorial analysis of variance (ANOVA) was used to examine the effect of BBPAS on the study variables. A mixed ANOVA showed significant changes (time effect) on cognitive process, F(1, 320) = 5.768, p-value = 0.017; behavioural process, F(1, 313) = 5.736, p-value = 0.017; and internal feeling, F(1, 312) = 6.050, p-value = 0.014. There was also a significant difference between groups on cons, F(1, 316) = 7.504, p-value = 0.007. A significant interaction effect was observed for stages of change, F(1, 319) = 7.861, p-value = 0.005; pros, F(1, 316) = 31.311, p-value = 0.001; internal feeling, F(1, 312) = 4.692, p-value = 0.031; and behavioural process, F(1, 313) = 7.312, p-value = 0.007. In conclusion, BBPAS was successful in improving four of the five constructs, and thus, should be recommended to be used in schools throughout Malaysia.

  16. New ways to cope with depression-study protocol for a randomized controlled mixed methods trial of bouldering psychotherapy (BPT) and mental model therapy (MMT)
    Kind L, Luttenberger K, Leßmann V, Dorscht L, Mühle C, Müller CP, et al.
    Trials, 2023 Sep 22;24(1):602.
    PMID: 37736688 DOI: 10.1186/s13063-023-07629-x
    BACKGROUND: Due to the growing gap between the demand and supply of therapeutic services for people suffering from depression, with this study, we are investigating the effectiveness and factors of influence of new approaches in group treatments for depression. Two previous studies have already identified bouldering psychotherapy (BPT) as an effective option. It combines psychotherapeutic interventions with action- and body-oriented bouldering exercises. Mental model therapy (MMT) is a new cognitive-behavioral approach for treating depression. It focuses on identifying cognitive distortions, biases in decision making, and false assumptions and aims to correct and replace them with useful mental models. We aim to investigate the effectiveness of the interventions compared with a control group (CG) and to assess the factors of influence in a mixed methods approach.

    METHODS: The study is being conducted as a randomized controlled intervention trial. Adult participants with unipolar depression are being randomized into three groups (BPT, MMT, or CG), and the first two groups are undergoing a 10-week treatment phase. CG follows their individual standard treatment as usual. A priori power analysis revealed that about 120 people should be included to capture a moderate effect. The primary outcome of the study is depression rated with the Montgomery and Asberg Depression Rating Scale (MADRS) before (t0), directly after (t1), and 12 months after the intervention phase (t2). Data are being collected via questionnaires, computer-assisted video interviews, and physical examinations. The primary hypotheses will be statistically analyzed by mixed model ANOVAs to compare the three groups over time. For secondary outcomes, further multivariate methods (e.g., mixed model ANOVAs and regression analyses) will be conducted. Qualitative data will be evaluated on the basis of the qualitative thematic analysis.

    DISCUSSION: This study is investigating psychological and physical effects of BPT and MMT and its factors of influence on outpatients suffering from depression compared with a CG in a highly naturalistic design. The study could therefore provide insight into the modes of action of group therapy for depression and help to establish new short-term group treatments. Methodological limitations of the study might be the clinical heterogeneity of the sample and confounding effects due to simultaneous individual psychotherapy.

  17. Fulltext Factor structure and internal reliability of breast cancer screening Champion's Health Belief Model Scale in Yemeni women in Malaysia: a cross-sectional study
    Noman S, Shahar HK, Rahman HA, Ismail S, Aljaberi MA, Abdulrahman MN
    BMC Womens Health, 2021 Dec 29;21(1):437.
    PMID: 34965865 DOI: 10.1186/s12905-021-01543-7
    BACKGROUND: The reliability and validity of the Champion's Health Belief Model Scale (CHBMS) used in assessing the belief of women regarding breast cancer (BC) and breast cancer screening (BCS) have been examined on various populations. However, the use of this tool has not been adequately assessed for its validity in ethnic minorities. This study assessed the validity and reliability of CHBMS by analyzing the factor structure and internal reliability of the factors among Yemeni women in Malaysia.

    METHODS: A survey was conducted among 103 female teachers from 10 schools. SPSS version 22.0 was utilized in analyzing the data. Descriptive statistics were computed for the socio-demographic characteristics. The Cronbach's alpha coefficients were used in assessing the internal reliability. The Exploratory Factor Analysis (EFA) was used to analyze the factor structure of the translated items. Parallel analysis was performed to determine the number of factors accurately.

    RESULTS: The alpha coefficients of the factors had acceptable values ranging between 0.76 and 0.87. The factor analysis yielded six and five factors for breast self-examination (BSE) and mammography (MMG), with a total explained variance of 47.69% and 52.63%, respectively. The Kaiser-Meyer-Olkin (KMO) index values of 0.64 and 0.72, and the Bartlett's Test of Sphericity (P = 0.0001) for BSE and MMG, respectively, verified the normality distribution and the adequacy of the sample size for EFA. All the items on each factor were from the same construct that were consistent with the number of factors obtained in the scale development study. The items achieved adequate factor loadings that ranged between 0.47 and 0.88.

    CONCLUSIONS: The translated version of the CHBMS is a validated scale used in assessing the beliefs related to BC and BCS among Yemeni women living in Malaysia. Healthcare workers could use the scales to assess women's beliefs on BC and BCS. This instrument could be used to test the effectiveness of the intervention programs.

  18. We'll never get past the glass ceiling! Meta-stereotyping, world-views and perceived relative group-worth
    Owuamalam C, Zagefka H
    Br J Psychol, 2013 Nov;104(4):543-62.
    PMID: 24094283 DOI: 10.1111/bjop.12006
    This article examines the implications of perceived negativity from members of a dominant outgroup on the world views and perceived relative group worth of members of disadvantaged groups. We hypothesized that concerns about the negative opinions a dominant outgroup is perceived to hold of the ingroup (i.e., meta-stereotypes) would undermine group members' views about societal fairness. We expected this trend to be mediated by recall of previous personal experiences of discrimination. We further hypothesized that members' views about societal fairness would predict their perception of the ingroup's worth relative to the outgroup - such that undermined views about societal fairness would be associated with lower perceived ingroup worth relative to the outgroup. Taken jointly, results from two studies using two real intergroup contexts support these hypotheses and are discussed in terms of their implications for the social mobility of members of disadvantaged groups.

  19. PTSD's latent structure in Malaysian tsunami victims: assessing the newly proposed Dysphoric Arousal model
    Armour C, Raudzah Ghazali S, Elklit A
    Psychiatry Res, 2013 Mar 30;206(1):26-32.
    PMID: 23017656 DOI: 10.1016/j.psychres.2012.09.012
    The underlying latent structure of Posttraumatic Stress Disorder (PTSD) is widely researched. However, despite a plethora of factor analytic studies, no single model has consistently been shown as superior to alternative models. The two most often supported models are the Emotional Numbing and the Dysphoria models. However, a recently proposed five-factor Dysphoric Arousal model has been gathering support over and above existing models. Data for the current study were gathered from Malaysian Tsunami survivors (N=250). Three competing models (Emotional Numbing/Dysphoria/Dysphoric Arousal) were specified and estimated using Confirmatory Factor Analysis (CFA). The Dysphoria model provided superior fit to the data compared to the Emotional Numbing model. However, using chi-square difference tests, the Dysphoric Arousal model showed a superior fit compared to both the Emotional Numbing and Dysphoria models. In conclusion, the current results suggest that the Dysphoric Arousal model better represents PTSD's latent structure and that items measuring sleeping difficulties, irritability/anger and concentration difficulties form a separate, unique PTSD factor. These results are discussed in relation to the role of Hyperarousal in PTSD's on-going symptom maintenance and in relation to the DSM-5.
