Validating distress thermometer tool screen
The Problem List (PL) can be used in addition to the DT to identify possible contributing factors, summarised into five categories: practical, family, emotional, spiritual, and physical.
Although the DT and PL has been well-validated in numerous settings with various cancer groups  very little has been written on the acceptability of the measure.
The primary aim of this study is to validate the distress thermometer and a modified problem checklist for use with AYA cancer patients, aged 15–25 years.
Specifically, we aim to 1) determine appropriate cutoffs for clinical referral on the distress thermometer; 2) investigate the content validity of the modified problem checklist; and 3) assess the clinical utility of the tool from the perspectives of both patients and health care professionals.
As such, there is currently no validated instrument to measure distress in this group.
In addition to validating the DT for AYAs, this study also looks at prevalence and predictors of distress for AYAs with cancer.
However, health professionals often fail to detect distress in their patients due to time constraints and a lack of experience.
Cancer can be a distressing experience for cancer patients and carers, impacting on psychological, social, physical and spiritual functioning.This study evaluates the Distress Thermometer (DT) with young people diagnosed with cancer.The DT is a widely used distress screening tool and has been validated with adults, but young people especially those under 18 years have previously been excluded from studies.The limited discussion indicates that in general, the DT is accepted and perceived as helpful and easy to complete by health professionals and cancer patients .(2008) surveyed oncology and palliative care outpatients and found that 95% of respondents did not find completing the instrument upsetting in any way and 86% did not consider any changes were required to its current form .
