A MIMIC Model Approach to Research in Geriatric Neuropsychology: The Case of Vascular Dementia

The goal of the current study is to demonstrate a new methodology that can be used in neuropsychological research concerning differential diagnosis research. The multiple indicators, multiple causes (MIMIC) model is a latent variable methodology which can examine group differences on individual tests while controlling group differences in global cognitive impairment. As a demonstration, neuropsychological data from 217 dementia patients were incorporated into a MIMIC model to examine the influence of cerebrovascular disease (CVD) upon (1) dimensions of global cognitive impairment and (2) upon individual tests after controlling for global impairment. The presence of CVD in dementia (i.e., vascular dementia [VaD]) was not significantly related to dimensions of global impairment. In addition, the presence of CVD within dementia did not significantly contribute to impairment on 9 out of 10 neuropsychological tests/subscales examined after controlling global cognitive impairment. These results are discussed in the context of current vascular dementia research, and are focused primarily upon the MIMIC model methodology and suggestions for its use in future research.     

A bridge between cultures: Linked ethnographic-empirical methodology for culture anchored research

Relatively little research in community psychology has explicitly focused on groups whose world views, values, and practices diverge from mainstream North American and social science culture. Furthermore, when research does include members of subcultural groups, the same research methodologies used to stydy mainstream populations tend to be employed. In the current article, it is proposed that a linked ethnographic—empirical methodology is critical for culturally anchored research of rarely studied subcultures which differ markedly form the dominant culture. The use of a linked ethnographic—empirical methodology in the study of a nontraditional religious subculture is described, and the study's primary findings summarized. Respective and combined contributions of the ethnographic and empirical (i.e., quantitative) research components in seven key areas are discussed: (a) selection of phenomenon to study; (b) generation of hypotheses; (c) culturally anchored measure development; (d) sampling; (e) analyses; (f) interpretation of findings; and (g) social action. Limitations of the linked methodology are discussed. The author thanks Julian Rappaport, Chris Murphy, Robert Serpell, three anonymous reviewers, and the editors of the special issue for their valuable feedback.     

A philosophical and empirical analysis of subjects' modes of inquiry in wason's 2-4-6 task

Investigations of hypothesis-testing behaviour typically conclude that subjects' methods are characterized by “confirmation bias.” However, these studies (a) relied exclusively upon Karl Popper's philosophy of science, (b) only described subjects' strategies via a falsificationist terminology, and (c) failed to determine subjects' precise intentions in the task situations. Alternative philosophies of science can be used to describe hitherto ignored aspects of rule discovery in Wason's (1960) 2-4-6 task as well as reinterpret findings from previous research. Using Wason's task, Experiment 1 adopted J. S. Mill's inductive methodology in order to assess better the extent of elimination in experimentation. While it was found that subjects did eliminate a large proportion of their hypotheses rather than merely confirm them, Mill's eliminative methods applied to this task failed to account for the entirety of subjects' behaviours. Experiment 2 examined subjects' methods in more depth by asking subjects during the task either to: (1) describe their procedures, (2) select from a list of methodology terms those that best characterized their methods, and (3) state on each learning trial their preferred hypotheses and their subjective assessments that those hypotheses were correct. Although subjects were generally unable to describe their methods of inquiry, they were able to typify them via the methodology terms as if their methods were tacitly held skills. Contrary to presumptions of previous research, analyses indicated that subjects were not testing particular hypotheses on every trial but were often examining possible instances of the rule “at random” or “different from ones examined” to that trial. It is also suggested that subjects' decisions to announce rules and their thematic lines of inquiry be given further consideration by researchers.     

The State of Dyadic Methodology: An Analysis of the Literature on Interventions for Military Couples

ABSTRACT

Military members and their spouses experience unique stressors compared with civilian couples, making them distinctively vulnerable to a number of marital and mental health concerns. However, the amount and quality of intervention research to guide treatment for military couples are unknown. Therefore, a systematic literature search of interventions for military couples was completed resulting in 10 articles that met the study's inclusion and exclusion criteria. Further, a rubric to assess dyadic methodology was created and utilized to determine the dyadic quality of the methodology of the sampled articles. The results of the systematic literature review revealed that (a) there are few evidence-based interventions for military couples in which both members of the dyad are included and (b) the methodology by which treatments are evaluated largely do not employ systemic or dyadic measures. Recommendations for future research with military couples includes the need for couple-focused interventions using experimental methodology, systemic theories to guide intervention and research, and appropriate dyadic assessment and analysis tools to determine the effectiveness of couple's interventions for military, reserve, and veteran populations.     

Narrative vignettes and online enquiry in researching therapist accounts of practice with children in schools: An analysis of the methodology

Aims: This article reviews a research methodology that uses an Internet mediated qualitative, narrative approach to provide in‐depth analysis of vignettes. The research sought to investigate the ways in which dramatherapists, based in different countries, understood the nature of therapeutic change in their work with children. Method: The article describes a qualitative approach to the generation of data by a combination of therapist‐authored vignettes, live, synchronous Internet mediated communication (aMSN Messenger) and email. Participants kept a diary of their response to the research and the article draws on this data within its analysis of the methodology. Findings: Samples of the data are used to analyse how such innovative, online methodology can develop effective access and relationships with geographically dispersed participants and as an effective way of investigating therapist practitioners' understanding of their practice.     

Basic human values: The ethos for methodology

This paper draws on the personal experiences of part of a research project where the original methodology was flawed and needed to change to properly encompass the lives and experiences of the people who the research was for, namely users of mental health services living in supported housing. The change in methodology involved a recognition that the research could not be termed ‘value-free’; that researchers are not objective. It is argued that it was important to demonstrate that the information obtained in the research was ‘valid’, and that despite the subjective nature of the research, there are steps that can be taken to convince others that the information received is ‘real’. It is further argued that the traditional approach to research of separating theory (or knowledge) from practice was not only inappropriate in this sort of research, but is a false notion in any sort of action research that aims to promote change. The importance of the influence and power of service providers in action research is recognised, as well as the constraints placed on short-term funded projects. It was important for the methodology to be non-oppressive so that researchers adopted an open and honest approach and for researchers to become involved with the research participants. The implications of this ‘involvement’ are discussed. There is a concluding discussion about whether non-users of mental health services can be considered as allies in research. It is argued that all oppressed groups need their allies and if the research is led by basic human values, then working alongside people who depend on services can lead to emancipatory outcomes.     

Inventing the wheel once more or learning from the history of psychotherapy research methodology: Reply to Gaudiano's comments on review

Gaudiano's criticism of one part of my review of ACT outcome research (Öst, 2008) is refuted on all issues but one. It is clear that the average amount of grant support for the ACT-studies was smaller than that of CBT-studies, even if the proportion of studies having grant support was not lower. However, that fact should only influence 25% (2 out of 8) of the methodology variables on which ACT-studies had lower mean scores than CBT-studies. It is not acceptable that a relatively new treatment, such as ACT, should be evaluated by more lenient criteria than already established therapies like CBT. If proponents of a new treatment wish to claim that their therapy is empirically supported then they have to accept to be evaluated by the APA Task Force criteria. It is time that ACT researchers start using the current psychotherapy research methodology.     

How Can We Improve Preventive and Educational Interventions for Intimate Relationships?

Improving intimate relationships with preventive and educational interventions has proven to be more difficult than originally conceived, and earlier models and approaches may be reaching their limits. Basic concerns remain about the long-term effectiveness of these interventions, whether they are reaching and benefiting couples most likely to need them, and how they might be exerting their effects. We identify six problems that we believe are hindering progress in the field, and for each we outline research findings that point to new ways forward. These problems include (a) the incomplete understanding of couple communication and unwarranted translation of communication findings into interventions; (b) the surprising stability of relationship satisfaction; (c) the powerful roles that personal histories, personalities, and stress play in determining relationship outcomes; (d) the difficulties involved in recruiting and retaining high-risk couples in intervention programs; (e) the lack of attention given to specific stages of relationship development in interventions; and (f) the tendency to deliver preventive and educational interventions in the same format as therapies for distressed couples. We conclude by noting that a large body of basic research about intimate relationships, and large-scale outcome research with diverse populations, hold great promise for advancing the field.

Researching the reintegration of formerly abducted children in northern Uganda through action research: Experiences and reflections

This paper presents experiences and reflections on the use of a participatory research methodology under the difficult conditions of a war situation in northern Uganda. We draw from two complimentary approaches in action research to explain our methodology while doing research on the reintegration of formerly abducted children. First, the experience oriented approach, which emphasizes the need to articulate experience as a basis for learning and knowledge. Second, the exemplary participatory approach which highlights the importance of enhancing empowerment and the need to find solutions for social problems. We find these two approaches useful for doing action research in a conflict area because of their emphasis on experience and empowerment respectively. In our research, experience is important because of the children's encounter with the Lord's Resistance Army (LRA) rebels that both needs to be understood and justifies reintegration. On the otherhand, empowerment is important for our assumption that the children's experience and encounter with the LRA has disempowering effects on them. We demonstrate the use of the approaches in our research by enhancing participation, balancing power relations and being aware of ethical issues while at the same time attempting to make the research valid inspite of the challenges.

Studying Survivors of Nearly Lethal Suicide Attempts: An Important Strategy in Suicide Research

T he series of articles in this special issue of SLTB from the Centers for Disease Control and Prevention (CDC) study of nearly lethal suicide attempts represents an important contribution to research on suicidal behavior. The investigative approach used is attractive, yet also challenging in terms of research methodology. In this commentary I take the opportunity to highlight certain aspects of this line of research as well as to comment on the specific findings of the CDC study and their relationship to existing knowledge. I also discuss the future potential for this research approach and further questions that might be addressed by it.     

Examining arguments against quantitative research: “Case studies” illustrating the challenge of finding a sound philosophical basis for a human sciences approach to psychology

This article offers a close examination of critiques of quantitative research by Michell, 2011, Marecek, 2011, and Morawski (2011). One goal is to show that these three critics actually share with most mainstream quantitative researchers commitments to the Cartesian framework, even though this is not obvious because Cartesianism can appear in different guises. As a result of these commitments, the three theorists advance criticisms of mainstream quantitative research that fail to identify its key failings, put forward flawed views about how we should conduct research, and offer misguided criticisms of an approach I advocate called explicitly interpretive quantitative research. Another goal is to use the examination of the three critiques as a vehicle for clarifying the participatory perspective, a philosophical viewpoint that departs from the Cartesian framework. With regard to research methodology, the participatory perspective provides the basis for explicitly interpretive quantitative research, leads to ideas about changes we should make in how we conduct qualitative research, and treats quantitative and qualitative research as fundamentally similar because both should be pursued as interpretive modes of inquiry. I suggest that my analyses of the three critiques of quantitative research – or “case studies,” as I call these analyses – also may prove useful to researchers and theorists who want to develop a human sciences approach to other issues besides research methodology by helping them (1) recognize when lines of thinking that seem to depart from the mainstream actually represent variants of Cartesianism, and (2) consider what the participatory perspective might have to offer if they were to use it as the philosophical basis for their efforts.     

CULTURAL DIVERSITY AND METHODOLOGY IN FEMINIST PSYCHOLOGY: Critique, Proposal, Empirical Example

This article calls for a revision in the methodology of feminist psychological research because cultural differences can neither be investigated nor integrated without methodological change. A methodology that combines etic (objective, behavioral) and emic (subjective, phenomenological) approaches was demonstrated in an empirical investigation. White women did not differ from women of color in self-ratings on several gender-role stereotypic terms (etic data). However, the two groups differed significantly in how they had defined and interpreted those terms while rating themselves (emic data), and these subjective, culturally constituted interpretations predicted the self-ratings.     

Accuracy, completeness, and consistency of emotional memories

Judges and lawyers often consider inconsistent testimonies to be inaccurate. We addressed this assumption by asking undergraduate students on 2 occasions to write detailed accounts of violent movie fragments they had seen. These accounts were evaluated in terms of accuracy, completeness, and consistency. Experiment 1 showed that accounts tended to be accurate. Moreover, first accounts were marginally more complete than second accounts. The number of inconsistencies between the 2 accounts was not significantly related to their accuracy. Experiment 2 sought to replicate these findings using a more emotionally upsetting movie fragment. Results were highly similar to those of Experiment 1 in that accounts tended to be accurate but incomplete. Inconsistencies were not significantly related to the accuracy of participants' accounts. In line with previous research, we found that accounts of emotional events can be highly accurate but tend to be incomplete. More importantly, inconsistencies cannot be seen as valid predictors of testimonial inaccuracy.

From the method of proofs and refutations to the methodology of scientific research programmes

The paper is an attempt to interpret Imre Lakatos's methodology of scientific research programmes (MSRP) on the basis of his mathematical methodology, the method of proofs and refutations (MPR). After sketching MSRP and MPR and analysing their relationship to Popper's and Poly a's work, I argue that MSRP was originally conceived as a methodology in the same sense as MPR. The most conspicuous difference between the two, namely that MSRP is fundamentally backward‐looking, whereas MPR is primarily forward‐looking, is due to the fact that Lakatos could not carry out his project in the full sense. I also explain why he could not.     

The Communication and Bioethical Training (CoBiT) Program for assisting dialysis decision-making in Spanish ACKD units

Healthcare professionals currently working in Advanced Chronic Kidney Disease (ACKD) units must cope with difficult situations regarding assisting patients with the dialysis decision-making process, and they are often untrained for these conversations. Although we have evidence from the literature that these skills can be learned, few professionals feel confident in this area. A Communication and Bioethical Training (CoBiT) Program for ACKD staff (physicians, nurses and allied health professionals) was developed to improve their ability and self-confidence in conducting these conversations. A four-stage study was conducted: (1) development of the CoBiT program, beginning with the creation of an interdisciplinary focus group (N = 10); (2) design of a questionnaire to assess self-confidence based on the areas identified by the focus group. The face validity of the instrument was tested using an inter-judge methodology (N = 6); (3) design of the format and contents of the program; (4) piloting the program. Thirty-six health professionals took an 8-h workshop based on role-playing methodology. Participants assessed their self-confidence in their communication skills before and after the program using self-report measures. The results show that after the program, participants reported significantly higher levels of self-confidence measured with a five-point Likert scale (p < 0.001). Participants felt that communication with colleagues of other professions significantly increased after the workshop (p = 0.004). The CoBiT program improves ACKD Unit healthcare professionals’ self-confidence in their ability to perform a specific communication task.     

Efficacy of the third wave of behavioral therapies: a systematic review and meta-analysis

During the last two decades a number of therapies, under the name of the third wave of cognitive behavior therapy (CBT), have been developed: acceptance and commitment therapy (ACT), dialectical behavior therapy (DBT), cognitive behavioral analysis system of psychotherapy (CBASP), functional analytic psychotherapy (FAP), and integrative behavioral couple therapy (IBCT). The purposes of this review article of third wave treatment RCTs were: (1) to describe and review them methodologically, (2) to meta-analytically assess their efficacy, and (3) to evaluate if they currently fulfil the criteria for empirically supported treatments. There are 13 RCTs both in ACT and DBT, 1 in CBASP, 2 in IBCT, and none in FAP. The conclusions that can be drawn are that the third wave treatment RCTs used a research methodology that was significantly less stringent than CBT studies; that the mean effect size was moderate for both ACT and DBT, and that none of the third wave therapies fulfilled the criteria for empirically supported treatments. The article ends with suggestions on how to improve future RCTs to increase the possibility of them becoming empirically supported treatments.
