Are research participants truly informed? Readability of informed consent forms used in research

Researchers typically attempt to fulfill disclosure and informed consent requirements by having participants read and sign consent forms. The present study evaluated the reading levels of informed consent forms used in psychology research and other fields (medical research; social science and education research; and health, physical education, and recreation research). Two standardized measures of readability were employed to analyze a randomly selected sample (N = 108) of informed consent forms used in Institutional Review Board-approved research projects at a midwestern university during the 1987-1988 academic year. Results indicate that informed consent forms are typically written at a higher reading level than is appropriate for the intended population and that there are no consistently significant differences in readability among areas of research or between college student and noncollege student participants. Due to the unacceptably high reading level of the consent forms, one must question whether participants can comprehend the information contained in the consent form.     

Exporting analogue behavioral observation from research to clinical practice: useful or cost-defective?

The special section on analogue behavioral observation (ABO) provided an in-depth review of various ABO assessment procedures. Despite their availability, however, these procedures are rarely used in clinical practice. This may result in part from the traditions on which most ABO assessments are based, from distinctions between clinical and research assessment environments, and from the need for more information about the cost-effectiveness of ABO strategies for meeting specific needs of clinicians in applied settings. Suggestions for bridging the research-clinical gap involve investigating more thoroughly when ABO does and does not provide useful information for various purposes in applied settings and increasing accessibility and cost-effectiveness of ABO procedures for practitioners.     

Should children decide whether they are enrolled in nonbeneficial research?

The U.S. federal regulations require investigators conducting nonbeneficial research to obtain the assent of children who are capable of providing it. Unfortunately, there has been no analysis of which children are capable of assent or even what abilities ground the capacity to give assent. Why should investigators be required to obtain the positive agreement of some children, but not others, before enrolling them in research that does not offer a compensating potential for direct benefit? We argue that the scope of children's research decision making should be based on the principles of respect for autonomy and nonmaleficence. These principles imply that the threshold for assent should be fixed at 14 years of age, and a dissent requirement should be adopted for all children in the context of nonbeneficial research.     

Evaluation of counselling in primary care: How can research be made more useful for practitioners?

The paper presents a literature review of research on counselling in general practice critiqued from the perspective of the Practice Counsellor. It is noted that existing studies all focus primarily on outcome of psychological interventions in comparison to routine GP care. The contributions and limitations of these studies are discussed, and the methodological difficulties of conducting controlled trials in this context are explored. It is proposed that future research on counselling in primary care needs to draw on the paradigm shift in psychotherapy and a range of alternative research methodologies which will be more likely to produce research of relevance to Practice Counsellors.     

Why are therapists indifferent to research?

In counselling and psychotherapy there is a serious research—practice gap. Why should research on the therapeutic process have such little impact? Five related factors are considered: (i) epistemology—reliance on experiential/personal knowledge; (ii) preciousness—reliance on nonaxiomatic truths; (iii) lack of theoretical rigour—looseness with which constructs are construed; (iv) non-Popperian logic—tendency to work within a theory and defend it; and (v) personalisation of theory—evaluation seen as criticism. The result is a proliferation of therapies rather than a refinement of therapy.     

Postgraduate research students: People in context?

This article seeks to explore learning, development and academic success, using postgraduate research students' experiences and relating them to submission and completion rates. The perceptions and circumstances of a sample of postgraduate research students from one cohort in a large civic university were examined via questionnaire and interviews. Significant associations between data gained via questionnaire and outcome of research study are presented, together with qualitative illustrations from comments and interviews with participating individuals. A developmental, sociocultural understanding of the learner is discussed. This supports a brief review of a package of practical measures designed to assist universities to support research students, especially those who may have difficulty negotiating the experience of research study, and their supervisors, and ultimately improve retention and submission rates.     

Making sense of social research: how useful is the Hawthorne Effect?

‘The Hawthorne Effect’ is a phrase frequently employed in textbooks and other academic discourse. It appears to have been coined over 50 years ago and alludes to the outcome of research undertaken two decades earlier. This paper seeks to elucidate how the term ‘Hawthorne Effect’ has come to be used. A variety of texts will be presented to demonstrate the many different and often contradictory meanings ascribed to the term. A consideration of Guerin's review of research in social facilitation suggests the complexity of issues that seem to be involved in the use of the term ‘Hawthorne Effect’ is such that greater precision is required. Ultimately, we conclude, the term has no useful role in the discussion of research findings. Copyright © 2006 John Wiley & Sons, Ltd.     

Family therapy research: What are the most important variables?

This report summarizes the results of a nearly day-long session of a group of experienced and distinguished family therapy practitioners and researchers. The task the group set for itself was to begin delineating the most important variables to attend to in understanding family therapy and evaluating its effectiveness. With full recognition that such a task could be only partially and tentatively accomplished in the time allotted, a great many such variables were outlined.     

Error Detection in Text: Do Feedback and Familiarity Help?

In the present study, the authors examined the extent to which familiarity and feedback (auditory and/or articulatory) might be beneficial to proofreading. Participants proofread unfamiliar and familiar (repeated) passages while (a) concurrently reading either aloud or silently, (b) concurrently listening to the passages being read to them, or (c) reading without either auditory or articulatory feedback. Errors were one-letter changes that transformed function words into contextually inappropriate words. Familiarity improved reading times largely irrespective of feedback, and it enhanced error detection only when auditory feedback was available to participants. Proofreaders' enhanced error detection in familiar text reflected a change in their sensitivity to errors rather than any change in the placement of the response criterion for reporting errors. These findings suggest that familiarity can produce two kinds of functional fluency, one involving speed of processing, which is largely independent of feedback, and the other concerned with accuracy of processing, which relies on feedback.     

How useful are landmarks when learning a route in a virtual environment? Evidence from typical development and Williams syndrome

The ability to learn a route through a virtual environment was assessed in 19 older children and adults with Williams syndrome (WS) and 40 typically developing (TD) children aged 6-9 years. In addition to comparing route-learning ability across groups, we were interested in whether participants show an adult-like differentiation between "useful" and "less useful" landmarks when learning a route and the relative salience of landmark position versus landmark identity. Each virtual environment consisted of a brick wall maze with six junctions. There were 16 landmarks in the maze, half of which were on the correct path and half on incorrect paths. Results showed that both groups could learn each route to criterion (two successful completions of a route without error). During the learning phase, the WS group produced more errors than the TD group and took longer to reach criterion. This was predominantly due to the large number of perseverative errors (i.e., errors that were made at the same choice point on consecutive learning trials) made by the WS group relative to the TD children. We suggest that this reflects a difficulty in inhibiting erroneous responses in WS. During the test phase, the TD group showed stronger recall of landmarks adjacent to junctions (more useful landmarks) than of landmarks along path sections (less useful landmarks) independent of each individual's level of nonverbal ability. This pattern was also evident in the WS group but was related to level of nonverbal maturation; the differentiation between recall of junction and path landmarks increased as nonverbal ability increased across WS participants. Overall, the results demonstrate that individuals with WS can learn a route but that the development of this ability is atypical.     

Animal research in psychology: declining or thriving?

From Dialog's PsychINFO database the number of studies with 6 species reported in the Psychological Abstracts was calculated for each year from 1967 to 1988. Also, the number of studies with an additional 11 species were calculated for each year from 1973 to 1988. A hand search in the Journal of the Experimental Analysis of Behavior and Learning and Motivation was also conducted to explore trends in studies on 12 species from 1970 to 1987. The numbers of studies on many species (e.g., baboons, bats, chimpanzees, dolphins, gerbils, guinea pigs, gorillas, hamsters, lemurs, mice, pigeons, rats, seals, and snakes) have remained stable. There has, however, been a steady decline in the numbers of studies on selected species (e.g., cats, dogs, and rabbits). Possible reasons for changing trends in studies on selected species include: increased costs, the cognitive emphasis in psychology, and arguably, animal rights activism.     

“Applied” research can be useful: An example

an example of how a practitioner can use his research skills to help a school district evaluate one of its projects is described. The practitioner is advised to become involved in “action” research despite the limitations of such research, and the example is presented as having implications for expanding the psychologist's role to that of a consultant to administrators, teachers, and parents.     

How useful are corpus-based methods for extrapolating psycholinguistic variables?

Subjective ratings for age of acquisition, concreteness, affective valence, and many other variables are an important element of psycholinguistic research. However, even for well-studied languages, ratings usually cover just a small part of the vocabulary. A possible solution involves using corpora to build a semantic similarity space and to apply machine learning techniques to extrapolate existing ratings to previously unrated words. We conduct a systematic comparison of two extrapolation techniques: k-nearest neighbours, and random forest, in combination with semantic spaces built using latent semantic analysis, topic model, a hyperspace analogue to language (HAL)-like model, and a skip-gram model. A variant of the k-nearest neighbours method used with skip-gram word vectors gives the most accurate predictions but the random forest method has an advantage of being able to easily incorporate additional predictors. We evaluate the usefulness of the methods by exploring how much of the human performance in a lexical decision task can be explained by extrapolated ratings for age of acquisition and how precisely we can assign words to discrete categories based on extrapolated ratings. We find that at least some of the extrapolation methods may introduce artefacts to the data and produce results that could lead to different conclusions that would be reached based on the human ratings. From a practical point of view, the usefulness of ratings extrapolated with the described methods may be limited.     

Publication trends in behavioral gerontology in the past 25 years: are the elderly still an understudied population in behavioral research?

The case is made that issues facing the elderly are problems of social importance that should be of interest to applied behavior analysts. An electronic review of eight prominent behaviorally‐oriented journals was conducted in order to examine the frequency of publications over the past 25 years that were concerned with issues related to aging. A total of 109 articles were devoted to aging across the eight journals, with about 30% of these involving participants with cognitive impairments. Results also indicate that each of these journals has published less than one article per year related to aging. The role behavior analysts can play in serving both the elderly and their caregivers is discussed. Copyright © 2008 John Wiley & Sons, Ltd.
