The aim of the current study is to pilot a novel intervention to help people explore their decision making around the use of neuroleptic medication. A case series design will be used, with outcome variables measured at multiple time points pre-, during- and post-intervention. Participants will also be asked to complete an evaluation interview post-intervention. The primary aim is to investigate the feasibility and acceptability of offering the intervention.

Many service users experiencing psychosis are prescribed neuroleptic medication as the core component of treatment. However, discontinuations rates are high, which may be influenced by poor response rates and scepticism about the value of medication.

Frequently people discontinue without professional involvement, which is associated with negative outcomes. It is a particularly high risk period for relapse, especially if withdrawal is done quickly. There is an urgent need to advance practices in helping service-users to make a decision regarding neuroleptic medication that can then be supported by clinicians.

Current interventions regarding medication use predominantly focus on increasing adherence to medication regimes using, for example, financial incentives. This raises ethical concerns over the potential for service users' priorities and preferences to be disregarded, leading to increased coercion and reduced empowerment for service users. The recovery movement emphasises the need to understand personal priorities when considering treatment options and informed choice and shared-decision making is promoted by government initiatives and practice guidelines.

Shared decision-making commonly occurs within physical health settings. Patient decision aids have been found to improve patients' knowledge of available options and help patients to have more accurate expectations of potential benefits and harms, reach choices that are more consistent with personal values and participate in decision making. Despite this, shared-decision making has not been adopted more widely and is particularly poor within mental health settings.

The current study aims to explore the feasibility and acceptability of an intervention aimed at helping service users in mental health services think about their own personal priorities and decision-making around medication use. Current psychological interventions, such as cognitive behavioural therapy (CBT) and motivational interviewing (MI), view decision-making in terms of individuals making cost-benefit analyses, which then informs their "planned" behaviour. Such interventions thus target the identification of desirable medication related behaviours and then help the individual to make those behaviours occur.

Perceptual Control Theory (PCT) offers an alternative framework in which to understand medication related decision-making and behaviour. PCT regards all behaviour as goal directed but states that individuals control their experiences (or input) not their behaviour (or output). From this perspective, behaviour is understood as a means by which an individual resolves discrepancies between how they currently experience something (a current perception) and the way they want that experience to be. There is recognition that people are usually unaware of many of the different priorities (or goals) they hold, although these priorities/ goals are often incompatible (in conflict). An intervention informed by PCT (Method of Levels; MOL) would, therefore, target increasing an individual's awareness of the different personal priorities/ goals they hold in relation to medication use. The intervention would focus on exploring conflict between personal priorities, as from a PCT perspective; conflict is what causes ambivalence or difficulties in being able to enact certain planned behaviours. The aim in the current study would be to use MOL to help people develop their awareness of what is important to them in relation to medication use, as opposed to focusing on planning specific behaviours.

The aim in the current study would be to use MOL to help people explore their decision around the use of neuroleptic medication. Traditionally the focus of a MOL session is determined by the client and can vary from person to person, however, for this study the sessions will be specifically focused on neuroleptic medication use. The sessions will aim to help people explore a range of thoughts and feelings about decisions around medication use and how these relate to other important life values and goals. Another key aim of sessions will be to help people develop awareness of conflicts in their goals so that they might begin to find potential resolution. Due to the nature of the intervention being very patient-led and idiosyncratic, the outcome will vary from person to person. The intervention does not attempt to increase adherence or encourage discontinuation to the neuroleptic medication. It aims to help people develop awareness of how they feel about using neuroleptic medication and how medication might relate to other things that are important to them in life.

If this is a feasible and acceptable approach to use then future research would explore whether prescribers could incorporate this approach to working in their consultations with service users.
