| First author of the study, Year | Country | Total sample/ Males | Illness Group | Study Design | Illness Perceptions Tool | Key Findings |
| | USA | N = 147 104 males | Relapsed/ Refractory CLL | Cross-Sectional | B-IPQ: Consequences, Timeline, Personal control, Treatment control, Identity, Coherence, Concern, Emotional representation | Consequences and emotional representations were positively associated with cancer-specific stress, depressive symptoms and fatigue. In addition, illness concern was positively associated with cancer-specific stress; identity was positively related to fatigue |
| | Austria | N = 92 57 males | CLs | Cross-Sectional | IPQ-R: Identity, Consequences, Coherence, Personal control, Treatment control, Timeline acute/chronic, Timeline cyclical, Emotional representations, Causes | There was a significant association between illness perceptions and HRQoL |
| | Portugal | N = 102 All males | Hemophilia | Cross-Sectional | IPQ-R: Timeline acute/chronic, Timeline cyclical, Consequences, Personal control, Treatment control, Coherence, Emotional representation | Stronger perceptions about the consequences were significantly associated with higher depressive symptoms |
| | USA | N = 332 203 males | HSCT recipients (Leukemia, Lymphomas, Multiple Myeloma) | Prospective, longitudinal | IPQ-R: Timeline acute/chronic, Consequences, Personal control, Treatment control, Coherence | The illness course (more acute) and less severe consequences during the post-transplant period predicted improved psychological well-being and fewer psychological symptoms. Belief in better understanding and control (treatment or personal), during the post-transplant period, predicted better psychological well-being and less psychological symptoms |
| | Netherlands | N = 993 608 males | NHL, HL, CLL | Population-based registry | B-IPQ: Consequences, Timeline, Personal control, Treatment control, Identity, Concern, Coherence, Emotional representations | More negative perceptions of consequences, increased symptoms and lower illness coherence were associated with more fatigue |
| | Israel | Ν = 30 25 males | MF (stage I) | Cross-Sectional | IPQ-R: Identity, Timeline-acute/chronic, Timeline cyclical, Consequences, Personal control, Treatment control, Coherence, Emotional representations, Causes | A positive correlation was found between illness coherence and QoL. Additionally, there was a negative association between illness coherence and depression |
| | USA | N = 259 171 males | CLL | Randomized Trial | B-IPQ: Consequences, Timeline, Personal control, Treatment control, Identity, Coherence, Concern, Emotional representation | The LPA representations predicted depressive symptoms, negative mood and cancer-specific stress after one year of continuous treatment |
| | Belgium | N = 75 52 males | MDS | Prospective observational Trial | B-IPQ: Consequences, Timeline, Personal control, Treatment control, Identity, Coherence, Concern, Emotional representations, Causes | There was a strongly negative correlation between concerns and emotional perceptions and HRQOL. There was also a positive and significant relationship between treatment control and HRQOL |
