the positions are changing when the effect of age,
trade area, vessel type and flag are brought into the
equation. The positive effect of being a commander
loses its previous significance, even if the coefficient
remains high. In terms of position, it is now only the
positive effect of being a cabin attendant that remain
significant concerning the perceived safety training
quality (PSTQ) after controlling for the additional
variables in the model.
Moving down to the added explanatory variables,
we can note that increasing age still has a significant
positive and linear effect on PSTQ. It also appears that
it is only sheltered trade that shows a significant
positive effect compared to near costal trade (which is
in the constant). Regarding ship types, only the effects
for offshore and road ferry are without significance.
All ship types show a positive effect except ships with
a maximum of 12 passengers which display a
coefficient significantly below the constant (which are
dry cargo ships).
At the bottom of the variable list, it appears that
the Swedish flag still has a positive and significant
effect on the perceived safety training quality. Below
the variable list the R-Square is presented. The R-
Square can be understood as the model's explanatory
value, where a value of 1 would mean that all
variation in the material is fully explained (which in
most cases would be impossible). When it comes to
analysis of survey responses, one can be completely
satisfied that the explanatory value has increased
from .019 in Stage I to .049 in Stage II.

4.2 Conclusion, future work and recommendations
The overall conclusion of the above analysis is that the
experience of the quality of safety training is
influenced partly by personal circumstances such as
position and age, and partly by external factors in the
work environment. But it is also clear that the effect of
the personal circumstances fades when the external
factors are entered. In that situation, it is only the
positive effects for cabin crew and age that remains
with both strength and significance.
Moving to the external factors and the trade area
category, it is only sheltered trade that show a
significant positive effect on the perceived training
quality. A possible explanation for this is that the
safety training is perceived to be easier and more
manageable on smaller ships with a smaller crew
where everyone knows each other well.
Finally, it may be added that Table 8 in Step II can
be used to predict the positivity in the experience of
safety training for different types of cases. Below, such
a prediction is exemplified with the case of a 60-year-
old cabin attendant onboard an ocean-going
passenger ship under the Swedish flag:
Constant: 42,114
+ 60 years old (0,143*60): 8,58
+ Cabin attendant: 12,702
+ Passenger ship: 7,036
+ Ocean trade: 3,676
+ Swedish flag: 3,539
__________________________________
= 77,647
Thus, the positive experience of safety training for
a 60-year-old cabin attendant onboard an ocean-going
passenger ship under the Swedish flag should
therefore, statistically calculated, be 77.647 on a scale
of 0–100. Then, of course, it is not certain that this type
of case exists in reality.
ACKNOWLEDGEMENT
I would like to express my gratitude towards the financial
support from the Swedish Mercantile Marine Foundation. I
would also like to thank Martin Viktorelius for help with
the initial survey design and collection of data. Moreover, I
like to thank the 2 365 respondents to our survey. Without
their input this study would not have existed.
