Treatment representation is an important factor of motivation and well-being during treatment (Horne, 2002).

The aim was to reveal the relationship between treatment representation and well-being in oncological patients first referred to chemotherapy.

40 oncological patients (10 males, 20-72 years old, mean age 50.49±13.75 years old, localizations included gastrointestinal tract and genitourinary system) first referred to chemotherapy filled Satisfaction with Life Scale (Diener et al., 1985), Scale for Positive and Negative Experiences (Diener et al., 2009), Hospital Anxiety and Depression Scale (Zigmond, Snaith, 1983) and Beliefs about Medication Questionnaire (Horne, 2002) that was slightly modified for the situation of chemotherapy. Disturbance of functioning was assessed in the interview as an opportunity to cope with job, home responsibilities or self-care (1-5-point Likert scale).

Cronbach’s alphas for Necessity and Concern scales were .69 and .76. Despite high appraisals of necessity of chemotherapy (mean 4.24±.53 on 1-5 Likert scale), concern about it was rather high (2.83±.82). Hierarchical regression analyses revealed that, after adjusting for disturbances in social functioning, concern about chemotherapy (but not its subjective necessity) predicted more severe negative emotions (β=.32, p<.05, ΔR2=10.0%). After control for general level of anxiety and depression, this relationship became weaker but marginally significant (β=.32, p<.10, ΔR2=8.4%).

Concern about chemotherapy in patients first referred to this treatment could be important predictor of well-being demanding for interventions aimed at stabilization of emotional reaction to chemotherapy regardless belief in its necessity.

There are wide-spread fears and expectations about radiotherapy in people referred to it that are not only unrealistic (Shaverdian et al., 2018) but also lead to poorer compliance with doctors and poorer satisfaction with treatment (Dong et al., 2014).

The aim was to reveal relationship between different aspects of subjective perception of radiotherapy in patients and their well-being.

34 patients first referred to radiotherapy, 23-70 years old (mostly females with breast cancer) filled modified version of Beliefs about Medication Questionnaire including items about radiotherapy (Horne et al., 1996), Satisfaction With Life Scale (Diener et al., 1985), Scale of Positive And Negative Experience (Diener et al., 2009).

Six scales were revealed by factor analysis in the structure of beliefs about radiotherapy (Cronbach’s alphas .74-.85): confidence in the effectiveness of radiation therapy, subjective need for it, lack of understanding of it, concern and general negative attitudes towards radiotherapy, doubts about the effectiveness of radiation therapy. Elder patients reported higher need for radiotherapy but also higher concerns about it (r=.35-.37). Concerns about radiotherapy were related to lower satisfaction with life and positive emotions (r=-.44 - -.34) while subjective need of radiotherapy was related to higher health anxiety (r=.71) and lower positive emotions (r=-.41).

Subjective concerns of patients regarding radiotherapy are related to poorer well-being and could be addressed in psychotherapy.
