Baseline Models of the Acquired Capability for Suicide Scale–Fearlessness about Death in Autistic and Non-Autistic Adults
| Not autistic group | CMIN/df | CFI | SRMR | RMSEA | pClose | AVE |

Model 1 = all scale items, no co-variances.8 Model 2 = model 1 with error terms co-varied “The fact that I'm going to die does not affect me” and “I am not at all afraid to die” and “The pain involved in dying frightens me” and “I am very much afraid to die”. Model 3 = all scale items those endorsing at least undergraduate level education (n = 242 not autistic, n = 233 autistic). Model 4 = exploratory model with item 4 removed “It does not make me nervous when people talk about death” and error terms co-varied between other negatively worded items. Bold indicates adequate or good model fit. CMIN/df <5, CFI >0.9, SRMR <0.09, RMSEA <0.1, pClose >0.05. AVE (Average Variance Extracted) >0.5 for adequate convergent validity.
