Demographic Variables Associated with Fear of AIDS and Homophobia

During the fall of 1985, over 500 introductory psychology students participated in a survey which employed different questionnaires to measure Fear of AIDS, Knowledge of AIDS, Homophobia, and Behavior Change. Opinions about public policy regarding AIDS and homosexuals, and background information such as sex and religious preference were also obtained. The results indicated that males who knew the most about AIDS were less fearful of the disease than were males who knew the least. No such relationship was found for females. In addition, respondents reported that they have been changing their behavior in light of the AIDS epidemic. This included some behaviors which were related to AIDS and some which were not. Finally, political and religious conservatives were generally more homophobic and fearful of AIDS than were liberals. In addition, conservatives generally preferred protection of the public as an approach to controlling the AIDS epidemic while liberals generally preferred to educate the public.     

An empirical study of a logistic mental test model

A logistic model developed by Birnbaum was tested in two ways. First, plots of proportions of subjects in different score categories were examined for consistency with the assumption of a logistic trace line, and especially for departures from the logistic which seemed due to guessing in multiple choice items. The results showed that guessing seemed to have little effect. Second, an attempt was made to predict the obtained score distributions of samples of subjects on six tests from item parameters estimated on independent samples. The fits were good in all cases, despite considerable differences between the tests, and some extremely odd distributions.Thanks are due to the Educational Testing Service for the generous provision of the data upon which Part I of this study and the analysis of the two set I tests was based and to J. Lumsden for the data of the four set II tests. I would also like to thank F. M. Lord and A. Birnbaum for valuable help in the formulation and conduct of the study.At the University of Michigan 1964–65.     

Interrogative suggestibility and delinquent boys: An empirical validation study

This study has several aims. First, to validate the Gudjonsson Suggestibility Scale (GSS) among delinquent and adolescent boys placed in an assessment and short-term treatment centre. Second, to test the hypothesis that adolescent boys are particularly susceptible to suggestions when they are ‘pressured’ by negative feedback and instructions. Finally, to investigate the hypothesis that suggestibility is related to memory recall and self-esteem. The GSS was administered to 31 boys (ages 11 to 16 yr) who had been independently rated by two teachers on measures of suggestibility and self-esteem. Suggestibility as measured by the GSS was found to correlate significantly with the teachers' ratings of suggestibility, supporting empirically the criterion-related validity of the GSS. Compared with young ‘normal’ adults the boys were no more likely to give in to suggestive questions than the adults, unless their performance was subjected to criticism and negative feedback. The results suggest that deliquent adolescents may be particularly responsive to interpersonal pressure during interrogation. The findings have important implications for police interrogation procedures.

College Students' Attitudes Toward Abortion: The Role of Knowledge and Demographic Variables1

The present study sought to determine the role that knowledge of abortion information and various demographic variables play in discriminating between those who approve and those who disapprove of abortion. Four hundred and fifty-four college students completed the Abortion Knowledge Test, constructed by the researchers, as well as an abortion attitudes questionnaire which asked subjects to indicate their degree of approval or disapproval of abortion in the case of 7 different scenarios. Attitudes toward abortion were significantly predicted by knowledge of abortion-related information above and beyond the significant influence of degree of religiosity, religion, and age. No significant gender differences were found. Respondents who indicated approval of abortion scored significantly higher on the Abortion Knowledge Test and tended to be older, less religious, and non-Catholic compared to those who disapproved of abortion.

An Isotonic Partial Credit Model for Ordering Subjects on the Basis of Their Sum Scores

In practice, the sum of the item scores is often used as a basis for comparing subjects. For items that have more than two ordered score categories, only the partial credit model (PCM) and special cases of this model imply that the subjects are stochastically ordered on the common latent variable. However, the PCM is very restrictive with respect to the constraints that it imposes on the data. In this paper, sufficient conditions for the stochastic ordering of subjects by their sum score are obtained. These conditions define the isotonic (nonparametric) PCM model. The isotonic PCM is more flexible than the PCM, which makes it useful for a wider variety of tests. Also, observable properties of the isotonic PCM are derived in the form of inequality constraints. It is shown how to obtain estimates of the score distribution under these constraints by using the Gibbs sampling algorithm. A small simulation study shows that the Bayesian p-values based on the log-likelihood ratio statistic can be used to assess the fit of the isotonic PCM to the data, where model-data fit can be taken as a justification of the use of the sum score to order subjects.     

Styles of decision making and their use: An empirical study

As interest has increased in teaching decision-making skills, so the need has grown for an empirically-derived classification system of decision-making behaviours. Six styles of decision making were accordingly isolated and validated by content analysis. Using cluster analysis, the styles were found to group into types along a passive-active continuum of involvement in the decision. Use of style was found to vary across situations, and to be related to the decision's perceived importance and the decision-maker's control in the situation.     

Age,and midcareer crisis: An empirical study of academics

This study develops an empirical basis for examining the midcareer crisis/ transition period of academic staff surveyed by questionnaire in four Australian Universities and Colleges. A total of 672 usable returns were obtained, representing a response rate of 52% of the academic staff. Principal components and factor analysis were used to establish latent social-role variables. Analysis of variance and covariance was applied using the latent social-role variables as dependent variables and occupational attributes such as age, sex, etc., as independent variables. The variable age was isolated from the larger study in this paper to illustrate empirically a midcareer crisis period for the population studied which is consistent with the general literature on midcareer crisis/transition.     

Demographic, habitual, and socioeconomic determinants of Internet addiction disorder: an empirical study of Korean teenagers.

The objective of this study was to analyze the demographic, socioeconomic, and habitual causes of juvenile Internet addiction. All do not agree that Internet addiction disorder (IAD) is a new type of addiction, but they agree that the IAD phenomenon has widely spread over recent years. This is also true in Korea. For this study, six schools in Korea were selected to collect data: two from Seoul, two from suburban areas, and two from rural areas. Two hundred and forty copies were collected out of some 700 copies distributed. Multiple regression models were employed to explore significant predictors of IAD. This study showed that at least two out of 100 teenagers in Korea are seriously suffering from IAD and that approximately one out of two is exposed to a kind of IAD. The causes of IAD are not only associated with habitual backgrounds for use of the Internet, but also demographic and socioeconomic backgrounds. Therefore, it can be said that the development of IAD is an interactive process between juveniles' habits of using Internet, and their demographic and socioeconomic backgrounds. As IAD progresses, a single type of intervention such as parent interventions or school interventions does not work effectively. Multimodal interventions are required to provide counseling services for individuals suffering from IAD.     

Alcoholism treatment and marriage and family therapists: An empirical study

This article reports on results of a mail questionnaire study conducted among 257 members of the American Association for Marriage and Family Therapy (132 respondents, response rate of 51%) on their attitudes toward alcoholism issues (acceptance of alcoholism as a disease, treatment philosophies used with clients and/or families, and acceptance and use of Alcoholics Anonymous as a resource). Results indicated that 69% of respondents (as compared with 42% formerly) considered alcoholism a disease after MFT education. A combination of individual, family therapy, and AA (81.1%); family therapy (66.7%); and AA only (60.6%) were most often used. Controlled use of alcohol by clients in treatment was believed to be unethical by 43.2%, legal by 39.4% and ineffective by 54.5%.     

The neurophenomenology of early psychosis: An integrative empirical study

BackgroundThe integration of various domains or levels of analysis (clinical, neurobiological, genetic, etc.) has been a challenge in schizophrenia research. A promising approach is to use the core phenomenological features of the disorder as an organising principle for other levels of analysis. Minimal self-disturbance (fragility in implicit first-person perspective, presence and agency) is emerging as a strong candidate to play this role. This approach was adopted in a previously described theoretical neurophenomenological model that proposed that source monitoring deficits and aberrant salience may be neurocognitive/neurobiological processes that correlate with minimal self-disturbance on the phenomenological level, together playing an aetiological role in the onset of schizophrenia spectrum disorders. The current paper presents full cross-sectional data from the first empirical test of this model.MethodsFifty ultra-high risk for psychosis patients, 39 first episode psychosis patients and 34 healthy controls were assessed with a variety of clinical measures, including the Examination of Anomalous Self-Experience (EASE), and neurocognitive and neurophysiological (EEG) measures of source monitoring deficits and aberrant salience.ResultsLinear regression indicated that source monitoring (composite score across neurocognitive and neurophysiological measures), with study group as an interaction term, explained 39.8% of the variance in EASE scores (R² = 0.41, F(3,85) = 14.78, p < 0.001), whereas aberrant salience (composite score) explained only 6% of the variance in EASE scores (R² = 0.06, F(3,85) = 1.44, p = 0.93). Aberrant salience measures were more strongly related to general psychopathology measures, particularly to positive psychotic symptoms, than to EASE scores.DiscussionA neurophenomenological model of minimal self-disturbance in schizophrenia spectrum disorders may need to be expanded from source monitoring deficits to encompass other relevant constructs such as temporal processing, intermodal/multisensory integration, and hierarchical predictive processing. The cross-sectional data reported here will be expanded with longitudinal analysis in subsequent reports. These data and other related recent research show an emerging picture of neuro-features of core phenomenological aspects of schizophrenia spectrum disorders beyond surface-level psychotic symptoms.     

Adult Age Differences in Tower of Hanoi Performance: Influence From Demographic and Cognitive Variables

We examined performance in a five-disk version of the Tower of Hanoi (TOH) puzzle, assumed to reflect executive functioning, in population-based samples ranging in age from 35 to 85 years (N ?=?2798). Univariate analyses revealed significant age effects across three TOH measures as reflected by an age-related increase in moves to solution, a gradual slowing of performance, and an increase in rule violations with advanced age. The age-related influence was eliminated, or reduced considerably, when controlling for demographic and cognitive background variables. Across the dependent measures, Block Design and a measure of episodic memory (recall) were the consistent predictors. No effects of education were detected, while significant gender differences, favoring males, were observed for two TOH measures. Taken together, the results suggest that age-related deficits observed in TOH performance reflects an age-related impairment in visuospatial ability in addition to impairments in executive functions.

Job Satisfaction Differences Between Military and Ex-Military Personnel: The Role of Demographic and Organizational Variables

This study examines differences in job satisfaction between military and ex-military personnel and examines the contribution of demographic, dispositional, and organizational variables to those differences. Analysis of data from 571 current New Zealand Army personnel and 171 ex-Army personnel found that Army personnel rated significantly lower than the latter on overall job satisfaction and on 7 of 15 job satisfaction facets. For both groups, high leader support, low job conflict and pressure, and high challenge, autonomy, and job importance were related to high levels of job satisfaction. For Army personnel, low levels of negative affect (a propensity to have a negative outlook on life in general), shorter tenure, and low centralization and formalization also contributed to higher levels of job satisfaction. For ex-Army personnel, income contributed to higher levels of job satisfaction. There were a number of significant differences, however, between Army and ex-Army groups on job satisfaction predictors. These results suggest that differences in job satisfaction between the two groups may be due to (a) different variables that contribute to job satisfaction for each group and (b) different demographic and organizational variables between the groups. Despite a number of limitations, the findings highlight potential future directions for the investigation of interventions in the work environment to provide enhanced psychological rewards for military personnel.     

Demographic factors affecting assertive and defensive behavior in preschool children: An ethological study

Observations were made of naturally occurring assertive and defensive behaviors among preschool children, using ethological methods. Four major classes of assertive behavior were studied: attempts to gain possession of objects, personal space intrusion, positive directives, and negative directives; in addition, behavior with aggressive characteristics was studied. The effects of the following demographic factors upon individual frequencies of assertive interaction initiation, probability of defense (to assertive initiations), and frequencies of aggressive behavior were examined: age, sex, birth order, sib group size, ethnic identity, number of parents in the home, father's occupational level, father's education, mother's employment (yes/no), mother's occupational level, mother's education. Results of the multiple regression analyses indicated the most widespread effects for ethnic identity, number of parents in home, age, and sex. The most assertive children tended to be nonwhite/black, older, male, and from single-parent homes. These results were fairly consistent across all classes of assertive behavior studied. There were only minor effects of social class on assertive behaviors, and the demographic characteristics of the sample indicated that the ethnic differences existed independent of social class. Limitations in interpreting the behaviors studied as indicating an underlying aggressive motivation are discussed.
