Objective: Childhood abuse (CA) is commonly associated with increased frequency of high-risk behaviours (HRB) in adolescence. Similarly, research has highlighted links between CA and blunted responses to reward. To date, little attention has been devoted to examine if altered reward processes may also be linked to increased engagement in HRB. To explore this hypothesis, this systematic review collated research that investigated the relationship among CA, reward processes and HRB. Specifically, the review addressed the question: Are HRB associated with altered reward processes in children and adults with a history of CA? Method: Behavioural and neurobiological studies on CA, reward processing and HRB in children and adults were selected from multidisciplinary and subject-specific databases published prior to the 1st of March 2016. The systematic literature search yielded 271 records with 198 non-duplicated results. Screening of 14 full-text publications led to five eligible studies synthesized in this review. Results: Results confirmed impaired reward learning and increased HRB in those with a history of CA. Associations of blunted anticipatory or consummatory reward processing and HRB in individuals with CA remained inconclusive. Conclusions: Reward learning appears to be associated with CA. Further research is required to explore the relationship between reward processes and HRB. Understanding CA from a neurodevelopment perspective is a critical step to developing effective intervention strategies to reduce HRB. Empirical Paper: Abstract Objective: Following childhood abuse (CA), adolescence often sees the onset of depression and high-risk behaviour (HRB). Despite the prevalence, little is known about underlying neurobiological factors linking CA and HRB. To address this gap, I examined if anticipatory and consummatory reward processing in adolescents with CA predict frequency of HRB, irrespective of depressive symptoms. Methods: Thirty-seven adolescents (M=17.08 years; SD = 1.86) participated in the study: 13 females with CA and current major depressive disorder (MDD), eight females with MDD and no CA, and 16 individuals with no CA and no MDD for comparison (control group). Adolescents completed the Card-Guessing paradigm to assess reward processing, while undergoing a magnetic resonance imaging scan. Neural region-of-interest responses in the striatum and pallidum were assessed during anticipatory and consummatory reward phases. Hierarchical regression models investigated if neural responses to reward were altered based on exposure to CA and if altered neural responses predicted higher use of HRB. Results: Data showed that (1) depressed adolescents engaged more frequently in HRB irrespective of history of CA, (2) anticipatory and consummatory reward processes were not altered based on a history of CA, and (3) blunted activation in right pallidum in anticipation of rewards predicted HRB irrespective of depressive symptoms. Conclusion: Although the current study did not confirm changes in reward processing following CA, blunted reward ‘wanting’ was linked to more frequent HRB. Findings are relevant to theories highlighting the critical role of the pallidum in perceiving cues as rewarding and in initiating goal-directed actions to obtain rewards.

Magister Artium (Social Work) - MA(SW) / A qualitative study was conducted to explore and describe the factors that hinder parent involvement in the High Five Life Skills Programme for at risk children. Parent involvement remains a challenging phenomenon, which affects not only the child, as an individual, but also the family in society. However, although parenting children is perceived to be an important responsibility, parents do not receive any formal training on how to be good parents. An explorative and descriptive research design was utilised. Data collection was done by means of semi-structured interviews and focus group discussions, with the parents/guardians and children in the High Five Life Skills Programme, as well as the teachers, who refer children to the programme. The method of non-probability sampling, employed in this study was purposive sampling. The sample was selected on the basis of the researcher’s own knowledge, as well as the purpose of the study. Data were analysed using the nine steps proposed by Creswell. The results highlighted six barriers that hindered parent involvement in the High Five Life Skills Programme, namely, Low self-esteem of parents/caregivers and children; Lack of communications between all relevant parties - caregivers, teachers and the facilitators of the High Five Life Skills programme; Lack of role models: Parents’ not being role models as their own negative behaviour hindered their involvement; Lack of an emotional bond between parents and children, coupled with absent fathers; Lack of parents’ parental skills and support networks; and the lack of resources and support with transport to and from meetings, as well as child care for younger siblings. The participants, especially the children, freely expressed themselves, and contributed to the results; thereby assisting the researcher to explore the barriers that hinder parent involvement in the High Five Life Skills Programme. It is anticipated that the results of this current study will form a basis for the High Five Life Skills Programme to develop strategies that respond to the needs of the parents and children involved in the programme.

The main aim of this thesis was to investigate decision making from a broad developmental perspective to clarify the role of the underlying mechanisms influencing it. Problem solving and cognitive inhibitory capacity were chartered initially through the use of hypothetical vignettes depicting socially relevant situations and through the use of the Stroop task, to tap into automatic inhibitory capacity. Initial assumptions that prefrontal cortical refinement would denote enhanced social problem ability were not confirmed. Experience emerged as distinct factor in problem solving/decision-making, with the youngest participants equally as effective in producing solutions to situations that they had the most experience in. A shift in development is observed with maturation denoting greater experience and this being applied directly to problem solving and decision-making situations. Education was identified as a possible contributory factor in decision-making and this was explored in a cross-cultural study that tapped into a non-schooled population. The results reinforced the centrality of experience in shaping decision-making. Decision-making in regards to the use of experience was then looked at through real life decision-making situations, where adolescents were asked to provide their knowledge or experience of situations where risk was involved. Adolescents possessed the necessary knowledge to distinguish between optimal and sub-optimal decisions in terms of the consequences that risk behaviours carried with them. However, many still chose to engage in risky behaviours. This paradox could also be explained by actual experience, with the suggestion that positive experience in a peer group was serving as a pool from which adolescents drew to make future decision-making. If risk behaviours were not experienced adversely, the likelihood of their repetition was high. Taken together the findings suggest that adolescents are well equipped with the cognitive skills to make decisions. Compared to younger children, they have more experience of a greater range of situations from which to extrapolate responses from. They also have a great deal of knowledge and information about the negative consequences associated with a range of challenging situations and risk-taking behaviours. However, when faced with decisions in the social domain, the behaviour of friends and perceptions of what other people are doing are powerful influences on adolescent decisions.

Thesis (DPhil (Psychology))—University of Stellenbosch, 2006. / This study has two purposes which are complementary: Firstly, an alternative prevention intervention was developed in order to introduce narrative group therapy as a therapeutical practice within preventative interventions in South Africa. Secondly, a training protocol was developed which can be used to train psychologists, counsellors, social workers, teachers and relevant persons to apply narrative group therapy as an alternative preventative intervention in their communities. In the context of this study, the personal stories of the adolescents who took part in this study reflect the problem stories of the Jamestown and Cloetesville community near Stellenbosch. After identifying 20 adolescents who experience problem stories with high-risk themes at two secondary schools in the respective communities, ten narrative group sessions were held, with social constructionism as philosophical approach. The training protocol was primarily of an experiential nature, consisting of 40 hours of training and 12 hours of supervision, with special focus on the personal stories of the four master’s degree psychology students who underwent training and facilitated the group therapy with the adolescents. For the purpose of this study qualitative research was done. During the development of the alternative preventative intervention, a qualitative description was given of the content of the personal stories of the adolescents within the interactional space of narrative group therapy and personal stories. The focus during this qualitative description was the following: • to establish whether the therapeutic process facilitated change, • to develop a new understanding of the therapeutic process by specifically focusing on applying narrative therapy in a group, and • to train and empower narrative-group-therapy facilitators to facilitate the narrative- group-therapy process. In this study two narrative-analytical research methods were used. Firstly, a qualitative narrative-analysis method was used to evaluate the psychotherapeutical transcripts. A part of these sessions was dedicated to this purpose and is presented in transcribed format. Secondly, the content-analysis method was applied: session data was examined, categories of the adolescents’ and students’ narratives were defined and thematic statements were extracted from the text, classified and sorted into categories or groups. This study provides supportive evidence that narrative group therapy as an alternative preventative intervention can be introduced as a therapeutic practice in South Africa. In addition, an effective training protocol was developed which can be used to train psychologists, counsellors, social workers, teachers and other relevant individuals to use narrative group therapy as an alternative preventative intervention in their communities.

(in English): The virtual world is becoming more a part of our reality nowadays. Even children are coming into it and they are losing the ability to distinguish between the real and the virtual world. The virtual world is then an absolutely natural thing for them, including the advantages and risks that it brings. The aim of this master thesis was to collect present opinions and views on the conception of specific primary prevention in the area of cyberspace, and to analyze the currently offered programs from certified organizations for schools in Prague. The basic question of research is: What kind of topics do these preventive programs deal with? The method of this research was based on data collection through document analysis, semi- structured interviews and observation. The results show, that the most developed and complex topics in current practice are cyberbullying and netolism, leading to prevention of potential risky use of social networks and safer use of internet. When the goals of preventive programs are expressed enough specifically and sufficiently and with respect to the child, then it mostly focuses on cognitive aspects of the personality. Based on the research at the end of the thesis, there are formulated recommendations for the implementation of other primary prevention topics in...

The thesis is focused on the specifics of the social service called low-threshold facility for children and youth and how the virtual communication can be used to work with the clients of the service. In the theoretical part the low-threshold facilities for children and youth, range, principles and target audience of this social service are described. Also function and purpose of communication is described and the specifics of mobile and virtual communication are characterised. The possibilities how to use the mobile and virtual communication in basic and special social consultancy are another topic. The practical part is focused on mapping how the area of Czech Republic is covered with the facilities supplying the social service called low-threshold facility for children and youth. It also includes a survey research reflecting actual practise in using the virtual communication as a tool when working with clients in these facilities. In current facilities mainly e-mail and Facebook social network are used sometimes also Skype, ICQ application and other social networks. Current practise is very diverse because a complex professional methodical basis to supply this service model is still missing.
