While career interventions show lasting benefits, real-life transfer is limited and mixed

The efficacy of career interventions is well-documented in vocational psychology, with robust evidence supporting their ability to reduce career decision-making difficulties and enhance self-efficacy. However, a critical methodological limitation persists: while studies frequently examine short-term effects on confidence and decisional difficulty, far fewer track whether these psychological gains translate into actual career choices or long-term vocational trajectories.

Historically, research has relied on proximal variable assessments—such as post-test measures of career adaptability—rather than distal outcomes like job placement, tenure, and long-term career satisfaction. This review critically examines the persistence of intervention effects over time and interrogates the extent to which academic or clinic-based gains transfer to real-life career contexts.

A rigorous and comprehensive systematic search was conducted across multiple major scientific databases, focusing on intervention studies that examine the longitudinal persistence of effects and real-world transfer outcomes. After applying relevance filtering and removing duplicates, the retained manuscripts were screened for eligibility based on predefined inclusion criteria. Ultimately, 12 peer-reviewed studies were included in the final synthesis, encompassing diverse intervention types—from future time perspective-based academic programs to manualized individual clinical counseling and group employability sessions for unemployed adults. Data were analyzed to differentiate between short-term durability (weeks to months) and longer-term vocational transfer (1 year+).

The persistence of intervention effects varies significantly based on follow-up duration and outcome measures:

**Weeks to months:** Interventions consistently demonstrate short-term maintenance. For instance, a future time perspective-based intervention with college students maintained elevated career decision-making self-efficacy and career search self-efficacy at a 4-week follow-up without decline from posttest levels (Park et al., 2018). Similarly, group employability interventions for unemployed adults mitigated the expected decline in employability resources over a 2-month period (De Carvalho et al., 2025).

**One year:** In clinical samples, outcomes are promising. Milot-Lapointe & Corff (2024) reported that 87% of clients who exhibited positive changes during manualized individual counseling continued to experience negligible difficulties and high career decision satisfaction 12 months later.

**Transfer to Real-Life Contexts:** Evidence bridging psychological gains to concrete vocational outcomes is methodologically limited. A longitudinal medical-school study observed that structured counseling coincided with reduced undecidedness and advanced training plans over one academic year, though it lacked a control group and did not track residency placements (Nguyen et al., 2025). Furthermore, while earlier career adaptability and self-efficacy predicted vocational identity clarity 20 months later among vocational graduates, specific job choices were not tracked (Kvasková et al., 2022).

The findings underscore a structural disconnect in career intervention literature: the conflation of psychological readiness with vocational realization. Several foundational papers (Lent & Brown, 2020; Gati & Kulcsár, 2021; Lent et al., 2019) conceptualize that strengthening self-efficacy and adaptability should logically support real-world transitions. Yet, empirical validation of this transfer is sparse.

While short-to-medium-term tracking highlights the stability of decision-making self-efficacy and reduced counseling difficulties, the lack of rigorous, controlled longer-term datasets (spanning 3-10 years) tracking actual occupational choices limits our understanding of intervention efficacy. The reliance on self-reported psychological constructs over objective career milestones represents a vulnerability in the field's evidence base.
