Acute and regular exercise as well as physical activity (PA) is related to well-being and positive affect. Recent studies have shown that even daily, unstructured physical activities increase positive affect. However, the attempt to achieve adherence to PA or exercise in inactive people through public health interventions has often been unsuccessful. Most studies analyzing the activity-affect association in daily life, did not report participants’ habitual activity behavior. Thus, samples included active and inactive people, but they did not necessarily exhibit the same affective reactions to PA in daily life. Therefore the present study investigated whether the association between PA and subsequent affective state in daily life can also be observed in inactive individuals. We conducted a pilot study with 29 inactive university students (mean age 21.3 ± 1.7 years) using the method of ambulatory assessment. Affect was assessed via electronic diary and PA was measured with accelerometers. Participants had to rate affect every 2 h on a six item bipolar scale reflecting the three basic mood dimensions energetic arousal, valence, and calmness. We calculated activity intensity level [mean Metabolic Equivalent (MET) value] and the amount of time spent in light activity over the last 15 min before every diary prompt and conducted within-subject correlations. We did not find significant associations between activity intensity and the three mood dimensions. Due to the high variability in within-subject correlations we conclude that not all inactive people show the same affective reactions to PA in daily life. Analyzing the PA-affect association of inactive people was difficult due to little variance and distribution of the assessed variables. Interactive assessment and randomized controlled trials might help solving these problems. Future studies should examine characteristics of affective responses of inactive people to PA in daily life. General assumptions considering the relation between affect and PA might not be suitable for this target group.

This study aimed to explore individual meaning systems in the course of a breast cancer disease to test the assumed positive relation between meaning and well-being and to investigate the relationship between post-traumatic growth and well-being. A total of 65 patients with breast cancer were examined 1 year after initial treatment and another year follow-up. Questionnaires addressed meaning in life (MLQ), anxiety and depression (HADS), satisfaction with life (SWLS), health-related quality of life (EQ-5D, EORTC) and post-traumatic growth (PTGI). Personal meaning systems were assessed using a qualitative method. In the personal meaning systems with well-being and relationships as the most frequently named meaning categories, the experienced gains far outweigh the losses sustained as a result of the disease. A stronger sense of meaning was related to lower levels of anxiety and depression, a higher level of satisfaction with life and better health-related functioning. Well-being and post-traumatic growth were mostly independent. Reported losses were strongly related to a poorer well-being. Cancer can induce a process of personal growth, and a strong sense of purpose could facilitate psychological adjustment. The often claimed correlation of post-traumatic growth and a better psychological adjustment is still lacking clear evidence, whereas losses proofed to be crucial.

Abstract. Experience sampling and psychophysiological ambulant assessment methods were employed to compare reactions to social stress using a laboratory stressor (The Trier Social Stress Test [TSST]) or a corresponding real-life condition (seminar presentation). Stress reactions were assessed by self-report as well as additional heart rate (AHR, i.e., heart rate increases corrected for physical activity and initial values) and were compared to a control condition in each group. Twenty-five participants gave a talk in a university seminar course and twenty-two participants took part in the TSST. The TSST elicited a greater overall physiological stress reaction as compared to the seminar presentation. However, analyses of dynamic AHR levels revealed that the groups of speakers showed different response profiles during the time course of the stress situations. AHR levels of both groups were similar at the beginning of the free speech. During the course of their presentation, seminar speakers downregulated their arousal level. The arousal level of TSST participants showed a further increase in the later portion of the TSST during the mental arithmetic task. Thus, the more prominent overall physiological stress reaction during the TSST as compared to the seminar presentation appeared to depend on different demand characteristics rather than on differences of laboratory versus real-life situations per se. The experience of emotional strain was greater in response to the social stressors than in response to control situations in both the TSST and seminar speaker group with no differential effects of the experimental setting (laboratory vs. real life). During the TSST procedure, salivary cortisol concentrations were also assessed. Significant correlations of AHR with cortisol level and subjective experience indicate that AHR measurement provides a valid psychophysiological indicator of social stress. These findings suggest that ambulatory assessment techniques successfully contribute to the validation of a common social stress task.

Current ambulatory technologies are highly relevant for neuropsychological assessment and treatment as they provide a gateway to real life data. Ambulatory assessment of cognitive complaints, skills and emotional states in natural contexts provides information that has a greater ecological validity than traditional assessment approaches. This issue presents an overview of current technological and methodological innovations, opportunities, problems and limitations of these methods designed for the context-sensitive measurement of cognitive, emotional and behavioral function. The usefulness of selected ambulatory approaches is demonstrated and their relevance for an ecologically valid neuropsychology is highlighted.

Negative affect caused by depression is known to produce cognitive failures during everyday activities. However, traditional neurobehavioral laboratory paradigms that assess affect-memory interactions are critical with respect to their ecological validity. To investigate the effects of negative affect on memory processes in everyday life, we applied a new interactive measurement method in order to detect heart rate increases without accompanying physical activity and to initiate stimulus presentations depending on the specific emotional state in healthy participants. Psychophysiological instability and the intensity of psychophysiological arousal at the time of encoding proved to be important predictors of memory performance in negatively valenced situations. We suggest that multimodal ambulatory methods provide an interesting new opportunity for assessing interactions of emotion and cognition in real life.
