Individual differences in habituation: Some methodological and conceptual issues

The personality correlates of habituation were investigated. A moderate intensity tone was presented 20 times on each of three sessions, and skin conductance and heart rate were recorded. There were no relationships between individual differences in rate of habituation and any of the personality dimensions assessed (which included, among others, manifest anxiety and introversion-extraversion). Some possible reasons are discussed for this lack of results, as well as for conflicting findings which fill the literature. Specifically, various methods of measuring habituation are examined and their interrelationships described. None of the measures derived showed adequate consistency either across sessions or over response modalities.     

Validity of the Sheltered Care Environment Scale: conceptual and methodological issues

The Sheltered Care Environment Scale (SCES) was developed primarily to measure social climate as an attribute of a setting. As such, the SCES was designed to maximize differences between facilities and minimize differences among individuals within a setting. However, Smith and Whitbourne (1990) assessed the validity of the SCES as a measure of individual differences in perceptions of a shared environment. Moreover, they redefined the content coverage of 2 of the SCES subscales (Independence and Physical Comfort), to encompass attributes the SCES is not intended to measure. In general, preliminary evidence indicates that the SCES subscales provide reasonably reliable and valid indices of the social climate of group residential facilities.     

The sociological study of suicide: methodological issues

This paper is a critical review of selected methodological issues in the sociological study of suicide. It first distinguishes between two broad research orientations: the micro and macro approaches to the subject. The paper than focuses on a critical assessment of the dominant macro-level methodology. Three recurrent problems are identified: measurement issues on four key variables (suicide and parasuicide, economic conditions, religion, and political conditions such as war); problems in studying the effect of mass media stories on suicide; and reasons why we need to adopt a cross-national method in order to test sociological theories for contextual effects. Partial remedies to many of these problems are discussed.     

The incremental validity of psychological testing and assessment: conceptual, methodological, and statistical issues

There has been insufficient effort in most areas of applied psychology to evaluate incremental validity. To further this kind of validity research, the authors examined applicable research designs, including those to assess the incremental validity of test instruments, of test-informed clinical inferences, and of newly developed measures. The authors also considered key statistical and measurement issues that can influence incremental validity findings, including the entry order of predictor variables, how to interpret the size of a validity increment, and possible artifactual effects in the criteria selected for incremental validity research. The authors concluded by suggesting steps for building a cumulative research base concerning incremental validity and by describing challenges associated with applying nomothetic research findings to individual clinical cases.     

Ethnic matching between therapist and patient in psychotherapy: an overview of findings, together with methodological and conceptual issues

This article reviews the empirical support for ethnic matching between therapist and patient in psychotherapy. The research has 3 sources: analog studies, archival studies of number of attended sessions and dropout rates, and process-outcome studies of psychotherapy. Clinical trials studying ethnic matching are absent. Empirical support for ethnic matching suffers from low validity and is inconclusive, with few studies of actual psychotherapy. The research is hampered by poor conceptualization of key concepts, difficulties in forming ethnically homogeneous groups for comparisons, and an abundance of uncontrolled within-group variables. Therapist variables, for example cultural sensitivity, are rarely investigated. There is a need for large-scale psychotherapy studies with well-defined key concepts in which the impacts of within-group and therapist variables are investigated.     

Comprehensive versus matched psychosocial treatment in the MTA study: conceptual and empirical issues

Addressed some factual inaccuracies and presented alternative positions on key issues raised in the article by Greene and Ablon (this issue) on the question, "What does the Multimodal Treatment Study (MTA) tell us about effective psychosocial treatment for attention deficit hyperactivity disorder (ADHD)?" The Greene and Ablon critique does not present for the reader's consideration the full range of findings from the MTA study, notably those most relevant to psychosocial treatment, and articulates a theoretical position that effective treatment requires matching treatment to children's assessed needs, an approach not taken in the MTA study. In this article, I present the full range of findings from the MTA study related to psychosocial treatment effects, correct the misperceptions that exist about the study based on limited reviews such as Greene and Ablon's, and review the empirical and experimental design issues that produced the decision by the MTA investigative team to study the effects of intensive, comprehensive psychosocial treatment. I argue that the questions asked by the MTA study about psychosocial treatment were important, relevant, and were addressed well in the MTA study design.     

Flashbulb memories: Conceptual and methodological issues

Abstract

Although flashbulb memory research is now well established, it is still not clear exactly what researchers are referring to as flashbulbs, and what is the best way to address the phenomenon. There are at least two ways in which the term “flashbulbs” is used, and at least two conceptual approaches that can be used to research them. The first usage corresponds to the bold theoretical conjectures put forward by Brown and Kulik (1977). The second results from empirical classification and intuitively lacks the essence conveyed by the first meaning. The two approaches concentrate on the cognitive and societal aspects, respectively. Although these are not incompatible, they make different assumptions and use different methodologies. We argue that research should be directed towards more unified theorising, and we describe methodologies appropriate for this approach.     

Re-dressing helping attire: methodological and interpretive issues

Using a study by Wilson and Kennedy in 2006 as a springboard, methodological and interpretive issues associated with helping people dressed differently and at various geographic locations are suggested. A plea for exploring more of the dynamics of helping as a communicative process is tabled.     

Patient variable biases in clinical judgment: conceptual overview and methodological considerations

Specific conceptual factors are presented as having contributed to the negative findings of past psychotherapy bias research. Among these factors are the restrictive nature of both the definition of bias and the model of the biased clinician. A review of published studies of several patient variable biases (e.g., gender, race/ethnicity, and age) indicated that bias may best be defined in broader terms and that its occurrence may be more circumscribed than originally conceived. In addition, the lack of a theoretical perspective in this area of research is noted and the applicability of some social cognitive processes is discussed. Methodological factors are also considered, and recommendations for future research are offered.     

Assessing treatability in mentally disordered offenders: A conceptual and methodological note

The assessment of treatability in mentally disordered offenders has rarely been addressed through empirical research, despite its frequent use in clinical and legal decision-making. We describe four necessary steps for establishing the requisite research base for treatability evaluations: (a) criterion specification, (b) the development of reliable measures, (c) the validation of these measures with treatment outcome data, and (d) the incorporation of environmental and base rate information.     

The influence of affect on self-focused attention: Conceptual and methodological issues

A number of investigators have suggested that affective states influence the focus of attention. One recent proposal is that negative moods increase self-focus. This review considers the evidence that bears on this hypothesis. Conceptual issues pertaining to the construct of self-focus are discussed first. Next, the various parameters that influence attentional focus are presented in order to provide a way of organizing the mood/selffocus literature. Studies that have used state measures of mood and self-focus are considered in this context. Methodological limitations of existing studies are discussed and directions for future work provided.     

Religiosity and adolescents' premarital sexual attitudes and behaviour: an empirical study of conceptual issues

A review of the literature concerning the relationship between religiosity and premarital sexual attitudes and behavior revealed inconsistencies in research findings and problems with methodology and operationalization of variables. A postal questionnaire to 527 16-18 year olds examined the associations between 6 models of religiosity (religious upbringing, denominational affiliation, ritual/behavioral, self-attitude/self-schema, and salience of religious identity) and personal sexual standards, attitudes towards sexually active others, virginal status, anticipation of sexual intercourse, and frequency of both coitus and noncoital sexual experiences over the previous year. A negative relationship between religiosity and a number of sexual attitudes and behaviors was observed, though nonsignificant relationships in the case of sexual experiences without intercourse suggested the maintenance of a technical virginity to accord with religious precepts. There was also some evidence that Catholic adolescents were more likely to be sexually active than non-Catholics when current religiosity was controlled for. The results lent strongest support to models which implicated self-conception either in terms of self-attitudes/self-schemas or the salience of religious identity. Implications of the study and suggestions for future research are outlined.
