Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
We will integrate "third wave" cognitive-and-behavioural components of the Acceptance and Committment Therapy (ACT) Triflex into a guided self-help programme (i.e., the three functional units of ACT – be present, do what matters, and open up) with the aim to increase psychological flexibility. Our six modules are: (1) Understanding emotional well-being in vision impairment, (2) Being present, (3) Doing what matters, (4) Opening up, (5) Effective communication, and (6) Wellness planning.

The programme will be delivered in three individual face-to-face and three individual telephone consultations, of up to 50 minutes in duration per session, by a clinical psychologist. Sessions are administered once a week for 6 weeks. Two face-to-face visits will be followed by a telephone consultation, which is then followed by one face-to-face session and the remaining two telephone consultations. The weekly manual content is to be followed sequentially when the participant chooses, which is followed by guidance from the clinical psychologist in their sesisons.

Each intervention session will be recorded and the clinical psychologist will write a reflection on what was or was not effective following each session, with a view to developing a list of key intervention activities. We will record the number and duration of the face-to-face and telephone visits performed by the clinical psychologist. We will also record the time it took participants to follow the intervention (i.e., how long it took to complete each weekly session). After each session, the clinical psychologist will ask participants to describe how, and the extent to which they have used any strategies or intervention materials (i.e., the self-help manual provided in large print or for use with adaptive technology, includes readings, worksheets, and a description of skills to be practiced). In the evaluation interview, we will ask participants to describe the manner in which they followed the self-help course and the manner and extent to which they practiced their skills (in writing, cognitively, discussion etc.). Together, this information will be used to develop a measure of fidelity that will explore adherence to the programme and translation of therapy into daily life.

Comparator / control treatment
Usual care at vision rehabilitaiton plus a referral to GP. Usual care at Vision Australia is access to vision rehabilitaiton services plus a referral to see a GP if a client presents with depressive symptoms. We will also include a new sample of 60 paricipants with vision impairment who do not have symptoms of depression or score less than 5 on the PHQ-9 (i.e., those who have "normal" "nil" or "healthy" level of depressive symptoms) as a comparison sample.

Participant evaluation of programme: In a separate telephone interview conducted within one month of the completed intervention and by a research assistant not masked to group allocation, participant views will be gathered on the programme content, convenience, delivery, participant-therapist relationship, and impact. Participants will be asked to rate the frequency, duration, format, delivery, content, materials, and perceived benefits. Response format vary from dichotomous “yes” and “no” to Likert 5-point scales as well as open ended questions. An example question is “The amount of information provided to me was…” “too much” to “too little.” Participants will be asked what their ideal distribution of self-help versus one-on-one sessions (includes telephone and face-to-face sessions) would be for the therapy dissemination ranging from 0 to 100%, and the qualitative benefits perceived from both. Participants will also be asked if any significant others (spouse, friends etc.) assisted them with the intervention or its implementation and how helpful this was.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Following the baseline assessment, participants will be allocated to one of the three pilot arms. Those with a score of 5 or greater on the PHQ-9 will be randomised using a computer generated random number sequence, generated and concealed (sealed opaque envelopes) by a research member not involved in conducting the assessments or delivering the intervention. The follow-up interviews (post-intervention at 3-and 6-months) will be conducted by a research assistant masked to participant assignment. Any breaches of masking will be recorded and reasons obtained.
