Participant characteristics
Table 2 presents the demographic characteristics of the final sample (N = 331). The sample comprised 65.0% male and 35.0% female respondents, with a relatively balanced distribution between leaders (51.7%, n = 171) and staff (48.3%, n = 160). The largest age group was under 30 years (46.5%), followed by 31–40 years (32.0%); 76.4% held undergraduate or postgraduate degrees. Respondents were drawn from a range of industries, led by technology and telecommunications (46.2%), and from organizations of varied sizes. This profile is consistent with the study's purposive focus on employees actively engaged in AI-related work.

Measurement model evaluation
Because AITC is modeled as a second-order construct, a two-step approach was applied40. First, the reliability and validity of the first-order constructs were evaluated using Cronbach's α, composite reliability (CR), and average variance extracted (AVE), as shown in Table 3. PS5 and AHTR4 were excluded due to low outer loadings, which improved the convergent validity of PS (AVE = 0.563) and AHTR (AVE = 0.619)36. All CR values exceeded the 0.70 threshold, and all AVE values surpassed 0.50. Although Cronbach's α for AP was 0.585, its CR (0.781) and AVE (0.547) remained within acceptable limits, and α values of 0.5–0.6 can be considered acceptable for short scales43. Discriminant validity was supported: all HTMT ratios (0.25–0.77) were below the conservative 0.85 threshold (Table 4)45, and the square root of each construct's AVE exceeded its highest inter-construct correlation under the Fornell-Larcker criterion (Table 5)44.
| Construct | | α | Composite reliability | AVE |
| AITC | AP | 0.585 | 0.781 | 0.547 |
| MTO | 0.731 | 0.848 | 0.65 |

Table 5: Discriminant validity of the first-order constructs (Fornell-Larcker criterion). Diagonal elements (bold) are the square roots of each construct's AVE; off-diagonal elements are inter-construct correlations. Discriminant validity is supported when each diagonal element exceeds all correlations in its row and column.
Because all variables were self-reported by the same respondents, both procedural and statistical remedies were applied49,50. Procedurally, respondents were guaranteed anonymity, the consent statement emphasized voluntary participation and the absence of right or wrong answers, predictor and criterion items were placed in separate survey sections, validated short scales were used to reduce fatigue, and attention checks screened out careless responding. Statistically, Harman's single-factor test51 showed that a single unrotated factor explained 30.99% of variance, below the 50% criterion49,52. As a more stringent check, a full collinearity assessment46 showed all VIFs below 3.3 (Table 1), suggesting no evidence of severe common method bias, although such diagnostics cannot conclusively rule out method variance46,47.
The significance of the upward dimension effects of the second-order formative construct (AITC) was assessed using bootstrapping with 5,000 resamples36,41. As shown in Table 6, the formative weights of AP_LVS (0.493, p < 0.001), MTO_LVS (0.492, p < 0.001), and PF_LVS (0.249, p < 0.001) were all significant, and all VIFs were below 3.3, indicating that each lower-order dimension contributes substantively to AITC without collinearity concerns. The final structural model was then estimated using the two-stage procedure41,42 (Figure 3).
| Formative indicator | VIF | Original β | Mean β | STDEV | t-value | p-value |
| AP_LVS → AITC | 1.418 | 0.493 | 0.489 | 0.094 | 5.232 | 0 |
| MTO_LVS → AITC | 1.457 | 0.492 | 0.489 | 0.092 | 5.333 | 0 |

Structural model and mediation analysis
Table 7 reports the path coefficients with p-values, sample means (M), standard deviations (STDEV), t-values, and 95% confidence intervals. AITC was positively associated with CS (β = 0.485, p < 0.001), supporting H1, and with PS (β = 0.338, p < 0.001), supporting H2. CS was positively associated with AHTR (β = 0.444, p < 0.001), supporting H3, as was PS (β = 0.179, p < 0.001), supporting H5. PS was positively associated with CS (β = 0.230, p < 0.001), supporting H6, and AITC with AHTR (β = 0.215, p < 0.001), supporting H9. The model explained 47.1% of the variance in AHTR (R2 = 0.471), 36.3% in CS, and 11.4% in PS.

Rows with arrows through multiple constructs (e.g., AITC → PS → CS → AHTR) report specific indirect (mediation) effects. Bootstrapping used 5,000 resamples.
The bootstrap results for specific indirect effects (Table 7) show that CS significantly mediated the AITC-AHTR relationship (β = 0.215, 95% CI [0.149, 0.290], p < 0.001), supporting H4, and PS likewise (β = 0.060, 95% CI [0.027, 0.102], p = 0.001), supporting H7. The sequential pathway AITC → PS → CS → AHTR was also significant (β = 0.034, 95% CI [0.017, 0.060], p = 0.002), supporting H8. Table 8 summarizes the hypothesis-testing results.

Out-of-sample predictive power was assessed with PLSpredict (10 folds, 10 repetitions; Table 9). All endogenous indicators returned positive Q2predict values, indicating predictive relevance, and the PLS-SEM model produced lower RMSE and MAE than the linear-model (LM) benchmark for nearly all indicators, the only exception being PS_4. These results indicate medium-to-high out-of-sample predictive performance for psychological safety, cognitive surplus, and AI-human task reallocation48.

Multi-group analysis
MGA examined whether the structural relationships differ between leaders and staff, who occupy different positions of accountability, job security, and task composition. As shown in Table 10, the associations of AITC with the two resource variables were significantly stronger among leaders: AITC → CS (leader β = 0.599 vs. staff β = 0.363; Δ = 0.236, two-tailed p = 0.014) and AITC → PS (leader β = 0.435 vs. staff β = 0.199; Δ = 0.236, two-tailed p = 0.043). These differences are practically meaningful: the AITC-CS association among leaders was roughly 1.6 times that among staff, and the AITC-PS association was more than twice as strong. The remaining direct paths (AITC → AHTR, CS → AHTR, PS → AHTR, PS → CS) did not differ significantly between groups (all two-tailed p > 0.19), indicating that once resources are formed, their associations with task reallocation operate similarly across roles. The group-specific bootstrap estimates (Table 11) further reveal asymmetric significance patterns in four pathways: PS → AHTR was significant for leaders (β = 0.234, p = 0.001) but not staff (β = 0.133, p = 0.064); the indirect path AITC → PS → AHTR was significant for leaders (β = 0.102, p = 0.005) but not staff (β = 0.026, p = 0.178); conversely, PS → CS → AHTR was significant for staff (β = 0.140, p = 0.001) but only marginal for leaders (β = 0.059, p = 0.054); and AITC → PS → CS was significant for staff (β = 0.057, p = 0.043) but marginal for leaders (β = 0.067, p = 0.065). Taken together, the psychological-safety route to task reallocation appears more direct for leaders, whereas for staff, psychological safety relates to reallocation primarily by enabling cognitive surplus, a pattern consistent with role differences in accountability and job-security exposure (H10a supported; H10b partially supported).

Table 11: Group-specific bootstrap estimates for leaders and staff. Standardized path coefficients (Original), bootstrap means, standard deviations (STDEV), t-values, and two-tailed p-values were estimated separately within the leader (n = 171) and staff (n = 160) groups, for all direct and specific indirect paths. Bootstrapping used 5,000 resamples within each group. AP = autonomous planning; MTO = multi-tool orchestration; PF = proactive feedback; CS = cognitive surplus; PS = psychological safety; AHTR = AI-human task reallocation; AITC = Agentic AI technological characteristics.
In sum, the measurement model met the reliability and validity criteria; AITC was positively associated with CS, PS, and AHTR; CS and PS mediated the AITC-AHTR association individually and sequentially; the model showed satisfactory out-of-sample predictive performance; and the associations of AITC with CS and PS were significantly stronger among leaders, whereas the paths from resources to task reallocation did not differ significantly between roles. Taken together, the results support the hypothesized resource-gain model and motivate the role-differentiated interpretation developed in the Discussion.
