Many adults with intellectual disabilities (ID) have depressive symptoms, which negatively impact their quality of life. A lot of of the non-medicinal forms of treatment are not or hardly suitable for people with ID. Bright light therapy (BLT) seems to be a good option. Earlier research has shown that BLT is applicable in this group and seems promising in terms of reducing depressive symptoms, without serious side effects. In part 1 of this project we investigate the implementation of BLT at Amarant. We will take the lessons learned into part 2 of this project: the implementation of BLT at Abrona. We will evaluate this process and the outcomes.

RECRUITINGacceptability
Acceptability (Proctor et al., 2011) is the perception among implementation stakeholders that a given treatment, service, practice, or innovation is agreeable, palatable, or satisfactory. This will be measured by interviews.
Time frame: three times during study, 3-4 months in between
appropriateness
Appropriateness (Proctor et al., 2011) is the perceived fit, relevance, or compatibility of the innovation or evidence based practice for a given practice setting, provider, or consumer; and/or perceived fit of the innovation to address a particular issue or problem. This will be measured by interviews.
Time frame: three times during study, 3-4 months in between
feasibility of the intervention
Feasibility (Proctor et al., 2011) is defined as the extent to which a new treatment, or an innovation, can be successfully used or carried out within a given agency or setting. This will be measured by interviews.
Time frame: three times during study, 3-4 months in between
fidelity
Fidelity (Proctor et al., 2011) is defined as the degree to which an intervention was implemented as it was prescribed in the original protocol or as it was intended by the program developers. This will be measured by interviews and by case report study.
Time frame: three times during study, 3-4 months in between
strategies
Implementation strategies are methods to enhance the adoption, implementation and sustainability of a policy or intervention. This will be studied with interview data and logs.
Time frame: three times during study, 3-4 months in between
Determinants
Barriers and facilitators to BLT, measured by interviews using the Consolidated Framework for Implementation Research (CFIR, Damschroder et al., 2009)
Time frame: three times during study, 3-4 months in between
Depressive symptoms
Depressive symptoms measured by the Anxiety, Depression, and Mood Scale (ADAMS, Hermans et al., 2008). It contains 28 items, each can be scored 0 to 3. Minimum score 0 and maximum score 84 and higher scores mean worse outcome.
Time frame: 1 year
Behaviour
Behaviour that could be linked to depressive symptoms measured by the Aberrant Behaviour Checklist (ABC, Aman et al., 1985). It contains 58 items, each can be scored 0 to 3. Minimum score 0 and maximum score 174. Higher score means worse outcome.
Time frame: 1 year
