Empirical research on online consumer theory has been examined under diverse contexts over the years. Although researchers from a variety of business disciplines have made significant progress over the past few years, the scope of these studies is rather broad, the studies appear relatively fragmented and no unifying theoretical framework is found in this area. In view of this, this study attempts to provide an exhaustive review of prior theoretical literature and to provide an integrative model of online consumer behavior. This framework not only provides us with a cohesive view of online consumer behavior, but also serves as a salient guideline for researchers in this area. The paper is concluded with a research agenda for future studies.

Hikikomori, which originated in Japan, refers to the condition where youths withdraw into the home and do not participate in society for an extended period of time. Recent updates on hikikomori presentation within the region were exchanged at a Hikikomori Round Table and Regional Symposium (HRTRS) discussion late 2017, leading to this perspective paper. Hikikomori presents as an overall homogeneous construct, while diversity in clinical presentation exists across East Asian countries. We examined the various presentations, risk factors, theoretical frameworks, and classification issues about hikikomori. In particular, specific risk factors have emerged to some degree across the region, while some are more locale specific. We propose that hikikomori youths have differential onset and developmental patterns, potentially resulting in heterogeneous presentation. We briefly summarized existing interventions in the East Asian region. Intervention strategies need to be tailored to different subtypes. A multicomponent approach would address complexity, multifactorial onset, and development of the condition. The HRTRS presented to participating countries the opportunity to collectively work toward a more universal definition of the hikikomori condition and explored innovative ways to shape existing service structures. Opportunities for participating countries described pertain to early detection of cases, adoption of assessment tools, and improved intervention services.

This study adopts the perspective of the Self-Determination Theory to look at the psychological experience of drug users and their decisions to take drugs or not, with particular emphasis on the concept of relatedness. To achieve this objective, a qualitative methodology was employed to explore the experiences of these drug users regarding how they take drugs and/or relapse. Theory-driven thematic analysis was employed to identify themes related to this topic. Results show that one’s psychological need for relatedness is an important determinant of whether one will take drugs or not, via the interaction mechanisms that exist in dimensions of affiliation and intimacy. While drug taking is a result of the modeling behavior existing in affiliated relationships, it is also a coping strategy for the ultimate satisfaction of psychological needs when human relatedness disappears. The implication is that significant others can develop unconditionally warm, caring, and empathetic supportive relationships with drug users, so as to enhance their fulfillment of psychological needs and reduce the risk of drug relapse.
