Aviation Safety Locus of Control - Military

Description:

The Aviation Safety Locus of Control – Military (ASLOC-M) is modeled after the civil version, ASLOC-C. The ASLOC-M was created by drafting a set of 89 items in which each of the items consisted of a statement regarding the extent to which the outcome of events is determined by internal and external factors (for example, skill versus luck). The items from the ASLOC-C were modified as required (such as replacing “pilot” with “Aviator”) to make them appropriate for an Army setting. An additional 80 items were also drafted, roughly evenly divided between items indicating a general internal orientation and an external orientation. The items were written to address the dimensions of personal efficacy, influence by others, influence by fate, and the element of luck or chance.

Number of Items: 89
Format: Likert scale: Strongly Agree (5) to Strongly Disagree (1).

Scoring:

Two scoring methods are reported. One method uses an a priori assignment of items to Internality or Externality factors. The other method uses the results of a principal components analysis.

Scores for all subscales are the sum of the items belonging to the subscale.

For the a priori scales, the scores are computed as follows:

These two commands compute the sums of ALL the internal and external items, based on an a priori review of the items.

Internal = lc1 + lc3 + lc4 + lc6 + lc8 + lc10 + lc11 + lc14 + lc17 + lc19 + lc24 + lc25 + lc30 + lc32 + lc33 + lc34 + lc37 + lc38 + lc41 + lc43 + lc45 + lc46 + lc50 + lc55 + lc62 + lc63 + lc64 + lc65 + lc66 + lc67 + lc68 + lc69 +lc70 + lc71 + lc72 + lc76 + lc77 + lc81.

External = lc2 + lc5 + lc7 + lc9 + lc12 + lc13 + lc15 + lc16 + lc20 + lc21 + lc22 + lc26 + lc27 + lc28 + lc29 + lc31 + lc35 + lc36 + lc39 + lc40 + lc42 + lc44 + lc48 + lc49 + lc51 + lc52 + lc53 + lc54 + lc56 + lc57 + lc58 + lc59 + lc60 + lc61 + lc73 + lc74 + lc75 + lc78 + lc79 + lc80 + lc82 + lc83 + lc84 + lc85 + lc86 + lc87 + lc88 + lc89.


The next two commands will compute the sums of the abbreviated Internality and Externality scales, based on an item analysis.

Int_Scal = lc41 + lc70 + lc65 + lc37+ lc67 + lc11 + lc46 + lc50 + lc63 + lc33 + lc81 + lc38 + lc1 + lc19 + lc62 .
.

Ext_Scal = lc52 + lc35 + lc85 + lc61 + lc84 + lc57 + lc87 + lc60 + lc58 + lc56 + lc39 + lc78 + lc88 + lc49 + lc36

To compute the factor scores:

FAC_1 = LC88 + LC87 + (6 - LC55) + LC82 + LC57 + LC52 + LC35 + LC74 + LC49 + (6 - LC62) + LC26 + LC79 + LC78 + LC60 + LC56.

FAC_2 = LC86 + LC39 + LC36 + LC52 + LC16 + LC5 + LC60 + LC20 + LC53 + LC7 + LC31 + LC12 + LC54 + LC13 + LC42.

FAC_3 = LC33 + LC50 + LC30 + LC45 + LC37 + LC71 + LC63 + LC66 + LC41 + LC32 + LC47 + LC46 + LC34 + LC70 + LC67.

FAC_4 = LC8 + LC65 + LC4 + LC14 + LC64 + LC11 + LC68 + LC19 + LC46 + LC15 + LC6 + LC10 + LC1 + LC17 + LC41.

FAC_5 = LC83 + LC89 + LC80 + LC78 + LC61 + LC85 + LC84 + LC79 + LC25.

FAC_6 = LC21 + LC22 + LC10 + LC3 + LC27 + LC9 + LC28 + (6 - LC81) + (6 - LC66).

Factor Composition:

Principal components analyses were conducted. Inspection of the scree plot suggested a six-component solution that accounted for 40.8% of the variance was appropriate. These six components were extracted and rotated, using Varimax to simple structure.
· Component 1 – Luck

· Component 2 – Externality

· Component 3 – Internality

· Component 4 – Accident Causality

· Component 5 – Fate

· Component 6 – Resignation

Reliability:

The coefficient alpha reliability indices for the six subscales are: .89, .87, .85, .82, .81, and .60, for the Luck, Externality, Internality, Accident Causality, Fate, and Resignation components, respectively.

Construct Validity:

Recent accident status was significantly correlated with the a priori Internality score (r = -.19), the Internality Component (r = -.16), the Accident Causality Component (r = -.14), and the Resignation Component (r = .23). However, career accident status was significantly correlated only with the Resignation Component (r = .26). Both recent accident status (r = .26) and career accident status (r = .18) were correlated significantly with the Army-HES. The Army-HES was also significantly correlated (r = .19) with the Externality Component.

Normative Information:

A priori Internality and Externality Scores

The 15 items comprising the Internality and Externality scales were summed to create the scale scores. Mean scores for the Internality and Externality scales were 54.94 (SD = 6.92) and 33.00 (SD = 8.27), respectively.

Means and Standard Deviations for the Army-LOC Component Scores.

Externality 15 192 18 56 33.86 7.34
Internality 15 198 30 73 56.06 6.69
