Depression och insomni är två vanliga former av psykisk ohälsa. I den här studien undersöktes om en bevisat effektiv behandling för insomni, (KBT-I), påverkade grad av depressiva symtom hos personer med konstaterade symtom på såväl depression som insomni. I studien kontrollerades för en minskning av nedstämdhet kunde tillskrivas en ökad fysisk aktivitetsnivå. En single case experimental design användes för ändamålet, med dagliga skattningar av sömn, nedstämdhet och fysisk aktivitetsnivå. Symtom på såväl insomi som nedstämdhet minskade signifikant hos tre av sex deltagare. Minskad nedstämdhet kunde inte förklaras av ökad fysisk aktivitetsnivå. Samvariation observerades mellan depression och insomni. Resultaten visar att insomni och depression kan påverkas av samma behandling, vilket antyder förekomst av gemensamma vidmakthållande mekanismer. / Insomnia and depression are two common mental health problems. This study investigated whether a proven effective treatment for insomnia CBT-I, would change the severity of depressive symptoms, for participants with comorbid insomnia and depression. It was controlled for, whether a reduction in depressive symptoms could be the result of increased physical activity. A single case experimental design, including daily measurements of sleep, depression and physical activity, was used as a means to answer the research questions. Symptoms of both depression and insomnia were significantly reduced for three out of six participants. Increased physical activity was not able to explain the decrease in depression scores. A correlation was observed, between depression and insomnia. The results shows that insomnia and depression can be affected by the same treatment, which implies existence of common perpetual mechanisms.

Separation anxiety is highly prevalent among intellectually and visually impaired individuals, yet little research has been done into its treatment in this population. Due to delayed cognitive skills, these individuals struggle to develop the abstract concept of person permanence, which is necessary to diminish separation anxiety. The first aim of this study was to investigate whether using technology alone or including caregivers was the most beneficial approach to developing person permanence using technology-assisted therapy. The caregivers received training in advance in an attachment-based protocol about securing attachment relationships with the participant. It was hypothesised that the inclusion of attachment figures in technology-assisted therapy would enhance the acquisition of the person permanence concept. The second aim of this study was to determine whether technology-assisted therapy in tandem with the participation of caregivers consequently decreased separation anxiety and challenging behaviour in an adult with intellectual and visual impairment. It was hypothesised that the subject’s anxiety and challenging behaviour levels would significantly decrease due to the intervention. The final aim was to determine how the caregivers and the participant experienced this intervention. It was hypothesised that they would regard it as a positive experience. This single-subject design used a pre-experimental quantitative approach. It was based on the familiar ABAB design and comprised six phases. Phase A served as baseline, giving the participants time to become acquainted with the technology. Phase B consisted of automated responses to the participant’s messages. In phase C caregivers directed the active reply. The daily messages were discussed when the participant and caregiver reunited, incorporating the attachment-based protocol. Phase B and C were repeated. Phase D followed after the devices were handed in. The technology was a specially adapted touch iPhone with an application comprising coloured emoticons. When the participant was physically separated from the caregiver, he could send happy, sad, angry or scared emoticons, or request help. The caregiver, who had a similar device, responded by sending a pre-determined response such as acknowledging the participant’s “I am angry” message with a “You are angry” message. Due to the association between anxiety and challenging behaviour in this population, standardised instruments were used to measure changes in these behaviours. Repeated measure ANOVA and a non-parametric Friedman test were used to analyse the data, specifically comparing phase B and C. Overall, the results showed that behaviour did significantly change over the course of the intervention. The frequency of the various iPhone messages sent by the participant was recorded daily. ANOVA contracts results demonstrated significantly fewer anxious and angry messages sent during the C phases compared with the B phases. The professional caregivers recorded the frequency and intensity of anxiety and challenging behaviours. The ANOVA contrast results showed a significantly lower frequency and intensity of these behaviours in the C phases compared with the B phases. A questionnaire was developed to evaluate the social validity of the intervention. The independent samples t-test demonstrated a significant difference between the mean scores rated by the caregivers at the beginning and the end of the invention. The participant and caregivers were positive about the intervention. Although the results cannot be generalised, it can be concluded that the inclusion of caregivers in technology-assisted therapy can serve as an invaluable aid to developing the person permanence concept. The findings also indicate that the anxiety and challenging behaviour levels shown by the adult with ID and visual impairment decreased due to technology-assisted therapy applied by caregivers, while responses to the social validity of the intervention were positive. / MSc (Research Psychology), North-West University, Potchefstroom Campus, 2015

Abstract Background/problem: That physical activity (PA) is important for good health and high quality of life is well known. PA also increases a person’s executive functions, ability to concentrate, solve problems and to learn. High school students (HSS) that lack motivation lose focus and are overrepresented as high school dropouts.  Aim: The aim was to examine the effects of a 20-minute walk, during lunch break, on HSS self-rated motivation and concentration during after-lunch-studies.  Method: The study had a multiple baseline single subject design. Six HSS estimated their motivation and concentration for “after-lunch-studies” for 20 school days. They also estimated their sleep quality, sleep time and how well rested they were when they woke up. During the intervention-phase they performed a 20 min walk on the lunch-break. The length of the baseline and the intervention varied between 5-10 days. Results: No differences were found for the participants when comparing the results from the first and second control period and the intervention period.  Conclusion: No effect on motivation and concentration was found in this study. A different design with more subjects and different exercise intensity might be better suited to evaluate the effects of physical activity on HSS motivation and concentration.

Objective: Recent research has supported the construction of a model of depression and anxiety in older adults ( > 60years), in which the decline in working memory with age is implicated in increasing propensity to engage in repetitive negative thinking, thereby predisposing older adults to anxiety and depression. The study detailed here intended to extend these research findings by exploring the efficacy and acceptability of a working memory intervention in older adults. Methods: The study employed a randomised multiple-baseline single case research design, in which six older adults participated in baseline assessment of mood, repetitive negative thinking and working memory. Participants then tracked their repetitive negative thinking daily throughout a baseline phase, the length of which was defined by the randomisation procedure. Following phase change, participants continued to rate their repetitive thinking daily, as well as engaging in a daily working memory training intervention. On completion of the intervention phase, outcome measures of mood, repetitive negative thinking and working memory were repeated. Full visual and statistical analysis of all data was undertaken to support exploration of the findings. Results: Results of the study indicated that that the working memory training program was unlikely to have elicited a significant impact upon participants’ working memory. However, two participants demonstrated reliable improvement in both repetitive thinking and mood. Analysis of relevant variables to predict the selective impact of the intervention was not fruitful, but may indicate that improvements in working memory underscore the improvements in thinking and mood, lending support to the proposed model. There appeared to be a small, non-significant decrease in daily repetitive negative thinking across five of the six participants. Conclusion: Further research is needed to identify factors that may predict response to working memory training within older adult populations. The research supports the on-going investigation of innovative working memory interventions within an older adult population, although results are not sufficiently robust to indicate wider adoption of these models within health services or as routine treatments for this population.

The current study examined the effects of language instruction with two preschool age students who are English language learners who have developmental delays using the incidental teaching method. Language targets were randomly chosen according to the language level of each student and the targets were either in Spanish (L1) or English (L2). The students were in a special education classroom and researchers worked with them one-on-one, using the natural learning environment to teach and to better implement learning objectives. Targets were withheld during play and students had to mand, tact, or use intraverbal skills to receive the item. Their reward was the object they desired after they manded, tacted, or used intraverbal language. The experimental effects were measured using a single case, repeated acquisition design. The intervention was maintained for five months. The results indicated that acquisition of English (L2) is acquired faster after Spanish (L1) has been appropriately taught. Implications for further research are discussed.

SCRDs are gaining ground in the counseling literature. Their flexibility, applicability to practice settings, and ease of interpretation make them an ideal design. Pairing SCRDs with qualitative case study offers the opportunity for a more complete understanding of the phenomenon of interest. This presentation will introduce attendees to this mixed method design. Design elements, as well as benefits and challenges experienced in the conduct of this research design will be explored.
