Interest in improving the financial capabilities of families with children is rising in the field of social work, although research on interventions promoting financial capability remains sparse. This study explores a financial social work intervention aiming to improve the financial literacy and economic self-efficacy as well as reduce financial anxiety among parents experiencing financial problems. Semi-structured interviews were conducted with professionals. Data were analyzed to inform the process evaluation. The results indicate that when conducting an intervention, it is important to ensure that professionals are aware of the integration of financial issues with psychosocial factors during social interaction.
