Internalized HIV stigma is prevalent and research on internalized HIV stigma has increased during the past 10 years. The aim of this systematic review was to synthesize research on internalized HIV stigma and relationships with various health-related variables in order to better inform the development of interventions aimed at reducing internalized HIV stigma. We reviewed 176 studies with a quantitative design reporting correlates that were peer-reviewed, published in English before January 2021, drawn from PubMed, PSYCHINFO, Web of Science, EBSCO, and Scopus.

Purpose: The web-based computer-tailored Kanker Nazorg Wijzer (Cancer Aftercare Guide) supports cancer survivors with psychosocial issues during cancer recovery. The current study investigates whether the 6-month effects in increasing emotional and social functioning and reducing depression and fatigue hold at 12 months from baseline. Moreover, it explores whether patient characteristics moderate the 6- and 12-month intervention effectiveness.

Objective: The aim of this study was to investigate whether problem-solving skills and perceived personal control over cancer recovery mediated the intervention effects on depression and fatigue of a web-based computer-tailored intervention for cancer survivors - the Kanker Nazorg Wijzer (Cancer Aftercare Guide).

Design: Patients were recruited through 21 Dutch hospitals (November 2013-June 2014). The mediation model was tested in a randomised controlled trial with an intervention group (n = 231) and a waiting list control group (n = 231).

Background: A fully automated computer-tailored Web-based self-management intervention, Kanker Nazorg Wijzer (KNW [Cancer Aftercare Guide]), was developed to support early cancer survivors to adequately cope with psychosocial complaints and to promote a healthy lifestyle. The KNW self-management training modules target the following topics: return to work, fatigue, anxiety and depression, relationships, physical activity, diet, and smoking cessation. Participants were guided to relevant modules by personalized module referral advice that was based on participants’ current complaints and identified needs.

Background: After primary treatment, many cancer survivors experience psychosocial, physical, and lifestyle problems. To address these issues, we developed a web-based computer tailored intervention, the Kanker Nazorg Wijzer (Cancer Aftercare Guide), aimed at providing psychosocial and lifestyle support for cancer survivors. The purpose of this article is to describe the systematic development and the study design for evaluation of this theory and empirical based intervention.

Objective: To explore cancer survivors' unmet needs in the first year after primary treatment, and to investigate the relationship between demographic, disease-related, and psychosocial characteristics and the number of unmet needs in different domains.

Methods: Cancer survivors were recruited through eight Dutch hospitals (November 2012-January 2013). In a cross-sectional survey, 255 survivors were asked about unmet needs across several domains (CaSUN) and demographic, disease-related, and psychosocial characteristics, comprising quality of life (EORTC QLQ-C30), psychological distress (HADS), mental adjustment (MAC), and problem solving (SPSI-R:S).
