Generalizing from Case Studies: A Commentary

This commentary responds to the articles assembled for the thematic issue Self-identity on the move: methodological elaborations (IPBS, 51 (2), June 2017). The issue points in two directions. Firstly, the articles investigate the way individual self-identity develops in changing social and cultural environments, specifically in the contexts of family, youth and migration. Secondly, the special issue is also interested in methodological elaboration, more specifically the question of how one can generalize from individual case studies, especially when looking at complex, multiscale, semiotic processes. This commentary particularly addresses the second point and uses the various cases in this issue (i) to better understand something of the larger intellectual debate around the question of ‘generalizing from case studies’, and (ii) to reflect on writing as a tool for indexing generalization. The commentary highlights five textual moves the authors use to make their findings relevant beyond the specifics of the local study.     

A Comparison of Paper and Computer Administered Strengths and Difficulties Questionnaire

The Strengths and Difficulties Questionnaire (SDQ) is one of the most widely used measures of young people’s mental health difficulties in research and clinical decision-making. Although the SDQ is available in both paper and computer survey formats, cross-format equivalences have yet to be established. The current study aimed to assess the measure’s equivalence across paper- and computer-based survey formats in a community-based school setting. The study examined self-reported measures completed by a matched sample of 11–14 year olds in secondary schools in England (589 completed paper version; 589 online version). Analyses demonstrate that the factor structure, although did not vary by survey format, resulted in poorly fitting models limiting the use of model based invariance testing. Results indicate that the measure does not operate similarly across different formats, with scale-level mean differences observed for the hyperactivity scale, which also affects the total difficulties score, with higher scores seen in the paper version. Responses to the impact supplement were also influenced by survey format, with higher impact in specific domains disclosed on the computer-based measure. Item-level differential item functioning was observed for four items in the measure; two from the prosocial scale where the DIF is large enough to affect the scale (DTF, ν² = 0.14). The inconsistency across survey formats highlights the need for more assessment of influences of different survey formats on young people, their perceived privacy and their mental health disclosures via different media. The findings also highlight the potential confounding effect of format when different methods of data collection are used, with a potentially substantive impact on cross-sample comparisons and within child clinical review.     

Independently Licensed Counselors' Work Values

Prospective clinical mental health counseling students need to know if their work values align with those of independently licensed counselors before investing their time and accumulating debt. Analyzing the work values of 463 independently licensed counselors in the United States, we found 89% expressing social (altruistic) work values and 22% expressing intrinsic work values. Independently licensed counselors want to help clients become fully functioning and self-actualized by maintaining unconditional positive regard, being congruent, and providing empathy. Clarifying these work values and their interaction can help prospective and current clinical mental health counseling students determine their future job role.     

Der Arztbrief

The right of inspection in the hospital documents, the hospital discharge report for example, is often refused to patients in in-patient psychotherapeutic treatment (psychiatry, psychosomatic and psychotherapeutic medicine) with reference to the protection of the patients themselves, their doctors or relatives. Within a systemic therapy approach patients of an acute psychosomatic care unit in a hospital the patients could inspect the report of their hospital treatment including all ?objective” and ?subjective” data of their hospital stay. The conversation with patients and their relatives about this report and modifications of the details and addresses of the report in case of patients’ objections is considered as a psychotherapeutic tool (narrative of doctor and patient) in order to improve the transparency of the diagnostic and therapeutic process and the insights in the psychosomatic mechanisms of the patient’s disease. We discuss our organisation of cocreating the hospital discharge report and our experiences with this type of patient-doctor-communication.

Long-term memory in pigeons: I. The role of discrimination problem difficulty assessed by reacquisition measures II. The role of stimulus modality assessed by generalization slope

Pigeons learned either an easy or a difficult line angle discrimination (Experiment 1) or wavelength discrimination (Experiment 2), and then they were given a reacquisition test of retention after delays of 1 min, 1 day, or 1 week. Both percentage of responses to the S+ in the initial 10-trial block and number of blocks to criterion showed a progressive memory loss which was greater for the difficult problem. These results extend recent findings by using a free operant rather than a discrete trial task and by varying problem difficulty by altering the dimensional separation between training stimuli. In Experiment 3, pigeons were given variable interval training with either a wavelength or a line angle stimulus, and then they were tested for generalization in extinction after delays of 1 min, 1 day, and 1 week. With both dimensions, the relative gradients became progressively flatter with increasing delay intervals. This replicates earlier findings and extends them to the line angle dimension. The evidence of substantial forgetting in the first 24 h in all three experiments suggests that operant free-response procedures are more sensitive to forgetting effects than are discrete trial tasks.     

Internal models in the cerebellum

This review will focus on the possibility that the cerebellum contains an internal model or models of the motor apparatus. Inverse internal models can provide the neural command necessary to achieve some desired trajectory. First, we review the necessity of such a model and the evidence, based on the ocular following response, that inverse models are found within the cerebellar circuitry. Forward internal models predict the consequences of actions and can be used to overcome time delays associated with feedback control. Secondly, we review the evidence that the cerebellum generates predictions using such a forward model. Finally, we review a computational model that includes multiple paired forward and inverse models and show how such an arrangement can be advantageous for motor learning and control.     

Influence of shape on haptic curvature perception

Curvature discrimination of hand-sized doubly curved surfaces by means of static touch was investigated. Stimuli consisted of hyperbolical, cylindrical, elliptical and spherical surfaces of various curvatures. In the first experiment subjects had to discriminate the curvature along a specified orientation (the discrimination orientation) of a doubly curved surface from a flat surface. The curvature to be discriminated was oriented either along the middle finger or across the middle finger of the right hand. Independent of the shape of the surface, thresholds were found to be about 1.6 times smaller along the middle finger than across the middle finger. Discrimination biases were found to be strongly influenced by the shape of the surface; subjects judged a curvature to be more convex when the perpendicular curvature was convex than when this curvature was concave. With the results of the second experiment it could be ruled out that the influence of shape on curvature perception was simply due to a systematic error made by the subject regarding the discrimination orientation.
