Positive psychotherapy effectiveness study and quality assurance

Positive Psychotherapy is a form of short-term psychotherapy based on an in-depth psychological approach, resulting from cross-cultural psychotherapy. After a brief introduction to some central elements of the theory of Positive Psychotherapy (PPT), the first results of the effectiveness study will be discussed in this paper. an assessment of alterations in symptoms, as well as changes in the way subjects feel and behave, which occurred in the period of time between the beginning and after the end of therapy will be presented here. In a longitudinal study, patients treated with PPT showed a distinct reduction of symptoms as well as improvement with regard to the way the subjects experience and behave compared to the control group, where no significant changes were observed. an additional cross-section comparison between the post-measures of the prospective assessment of PPT patients and retrospective assessments of PPT patients was carried out. No significant differences between the assessments made directly after finishing PPT and the assessments made within three different time spans after finishing PPT (a) 3-10 months; b) 10 months-4 years; c) 4-5 years) were found. This finding is viewed as an indication of the lasting stability of the therapeutic effects of PPT, which can still be detected up to five years after finishing PPT.     

Effects of acute bouts of exercise on cognition

A review was conducted of studies that assessed the effects of acute bouts of physical activity on adults' cognitive performance. Three groups of studies were constituted on the basis of the type of exercise protocol employed. Each group was then evaluated in terms of information-processing theory. It was concluded that submaximal aerobic exercise performed for periods up to 60 min facilitate specific aspects of information processing; however, extended exercise that leads to dehydration compromises both information processing and memory functions. The selective effects of exercise on cognitive performance are explained in terms of Sanders' [Acta Psychol. 53 (1983) 61] cognitive-energetic model.
