Enhancement of Quality of Work And Life

Work participation is essential for quality of life, providing purpose, social interaction, financial security, and shaping social status. Work participation is increasingly compromised in people with slowly progressive chronic disorders (hereafter referred to as progressive disorders). This negatively impacts their quality of life. Early work-related support, focused on sustainable work-retention, has the potential to enhance work participation in people with progressive disorders. Therefore, this study investigates the (cost)effectiveness of the Preventive Participatory Workplace Intervention (PPWI), a personalized work intervention to enhance sustainable work participation. The investigators perform an 18-month randomized controlled trial (RCT). In addition, the investigators perform a process evaluation and an economic evaluation alongside the RCT. 124 Dutch working persons with three types of movement disorders (Parkinson's Disease (PD), cerebellar ataxia (CA) and hereditary spastic paraparesis (HSP)) and with slowly progressive neuromuscular and mitochondrial disorders will be included.

Inclusion Criteria: * having a diagnosis Parkinson Disease, cerebellar ataxia, hereditairy spastic paraparesis, or a slowly progressive neuromuscular or mitochondrial disorder, confirmed by the treating physician (e.g. neurologist, rehabilitation physician) * aged 18-65 years; * being employed for at least 8 hours per week (at baseline). This also includes individuals who have reduced their working hours until reaching this threshold of 8 hours per week. Working time may be distributed across multiple working days; * having the intention to continue to work during the study period of 18 months, to prevent inclusion of participants who plan to retire within the 18-month RCT period; * being open to talk to the employer or manager about any changes or limitations in work performance (disclosing the diagnosis is not required, by law). Exclusion Criteria: * individuals who are at the beginning of a sick leave procedure (under the Gatekeeper Improvement Act; Wvp); * being fully self-employed. Partial self-employment in addition to paid employment is allowed, on the condition that the paid employment accounts for more than half of the total weekly working hours; * having a second employer for over eight hours per week; * proficiency in the Dutch language is not sufficient; * severe comorbidity or health-related event that will hamper compliance to the protocol, e.g. in case of a severe cognitive impairment, a relatively abrupt transition to a very progressive manifestation of the disease, a planned surgery.
